Thanks a lot for making this video! It was really helpful with my problem. The CD wouldn't eject. It was hitting the inside of the plastic bezel. It turns out that a worker forgot to put one of those blue rubber damper feet on the drive. So it was sitting too low. Luckily, the blue damper was sitting right there on the floor of the case, so I just put it on properly and now it works perfectly! Thirteen screws and the problem is solved. Thanks again!
Best clock radio I ever owned. Some Bose stuff may be over rated, but this radio unit is amazing and worth every penny. The only negative I have for it is the mandatory remote control to operate the clock alarm etc. Nothing wakes you up faster than cursing/searching for the remote you knocked off the nightstand that bounced under the bed when you just wanted to hit snooze. Nice transformer in them too BTW.
I just bought this same model and it exhibited the same behavior - buzzing in right channel and speaker pushed out continuously. I went to Digi-Key online and ordered the part and just finished putting it in today and VOILA! The sound comes from both speakers now. It was a carbon copy of this video. Thank you 12voltvids! I would not have known how to fix mine.
Thank you 12voltvids for an instructive video. Random question regarding the Boston Pops CD you played. Could you tell me the name of the album this CD was from ?
I found a Bose Wave AWRCC5 someone had dumped. I decided to upgrade all the capacitors and power amp. I found your video very informative, especially on how to remove the TDA7376B. I devised a way of removing the screw holding the heatsink. I cut a slot in the (threaded end) of it using a dremmel cut-off disk, then simply used a flat blade screwdriver to screw it clockwise which is anti-clockwise from the head end.
The same way I did by cutting a slot on threaded end of the screw holding the heat sink ,but unfortunately the one half of the threaded end of the screw holding heat sink broke when I was screwing it clockwise with a flat screw driver. I don't know how to remove the screw holding the heat sink.
40 seconds into it and I watch your Channel all day long! I'm going to take a guess and say capacitor possibly? But I'll kick back now, eat some food and enjoy the show! Maybe learn something new😆👍 * Edited after video* I'm happy to see that I was wrong! I was thinking since you could still hear music in the background, it wasn't the amplifier, possibly a capacitor in the power supply,? but then you showed the speaker popping out & wow that did not look right! I got to learn something new again from you today Dave. thank you! And thank you for that tip about everything goes into the Box for later, so you don't lose anything! You definitely need one of those fancy desoldering guns. I would like to get one for myself.
Great Video, I have Bose wave radio awrc-1p - The bass speaker has less sound than the other side, also when i turn the volume up same speaker gives out a same noise as you tested a speaker in your video. any suggestion how to fix it
Great video! , , I have the same unit . At first I was able to pare it with several laptops and cell phones. Then over time it lost it's ability to connect to any of them , , I'm guessing that the various software updates on these devices may be the issue , , Any experience with this issue? , , any advice would be appreciated.
Any suggestions to how to soften the bass on a 2012 Bose Wave III ? I bought mine used recently and I love it other than the dang bass. I have it set in the middle of a large room, away from corners and walls....
I recently got a Bose Acoustic Wave System, and found this video by that search. I'm sure the units couldn't be more different inside, but I found this video quite enlightening. Liked and subscribed. Great work!
Many changes for sure. I am just kicking back listening to my stereo right now. It has 4 12ax7 and 4 el34 tubes in it and my speakers are the size of a small car. There is really nothing like the sound of really big speakers and a good clean vacuum tube amp. Sound like the musicians are in the room. With me. Don't get me wrong the small systems sound good, but none hold a candle to a pair of speakers with 14" woofers . A big speaker doesn't have to work very hard to move a huge mass of air and my amp is probably putting out perhaps a watt or 2 and filling the entire room.
I've got one similar to this but it has a panel with buttons for everything on top. Many if not most of the buttons don't work anymore, Mainly just the volume buttons I guess. I'm trying to figure out how to remove the cover over the button panel. Thanks.
I love my Bose Wave Radio, But It seems to be losing a few minutes every week or so. We haven't had any power outages lately so what might be causing the time loss? And is there any way to adjust it? I've changed the 9 volt battery underneath the unit and it's the same problem.
Hi on the off chance, would you know what battery is in the Bose soundlink colour and where to get one not one video on the replacement of the battery. my best your video and sound is 7/10 v 7/10 s
Good video. I have this Bose wave system but no sound at all I just find out last week not working anymore they great system also. Do you think sir I can fix it following what you done? Thank you.
I have a Bose cd3000 and it hums slightly when off. I wonder if it’s the transformer, capacitor or amp chip on the power board. The hum does go away once the unit is turned on. Also the dc input from the power Case works fine. It’s just when it connected with an AC line and off that it hums.
The back of the sound dock speaker drivers, which are identical, say 1 cent. That seems impossible. Do you have any idea what else the cent symbol, (c with a line through it) would mean?
Great video. I have a problem with the infrared receiver inside bose music AWRCC 7 system. Because I have 2 such radios that support the same remote control, the fault is in the receiver. In place of the Q6500 I have an IR receiver with 4 pins below 3 holes on the display board soldered. what is the symbol of this IR receiver and how to replace it. On the print side it is as if soldered into one hole, which is connected to two of the three holes under the Q6500. Please advise what to do in this case. I can send photos of the tile, but I don't know how. Best regards and good health, Jerzy
Thanks for a great video. I just picked up a new Wave SoundTouch Music System IV, and can report this unit is now being "Made in Mexico". As this is their latest and greatest Wave Radio, it doesn't auger well for continued assembly in the U.S.A.
+smsstuart What a surprize! Just like everything else these days. I am sure the quality will show. I know the 321 system I serviced the subwoofer / power supply was made in Mexico, but the head end, that is the amplifier / DVD player was made in USA, but the actual DVD drive was from Taiwan, and that was where the problem was, a broken plastic gear. Blackberry used to make their phones in Canada, and finish them off in Mexico, but that too has now shifted to China.
I found a source online that makes made-to-order ribbon cables. Sorry, but I don't have a link. Made to width of ribbon and width between individual conductors and number of conductors.
This one has a 120Hz hum and a DC offset. I've got a Wave Radio in the shop that's got a 60Hz hum and no offset, and no audio gets through. Where did you get schematics and parts?
Hi, I have a lifestyle 5 model 614810, everything works perfectly, but little by little did you lose the tuning of the radio? Will I have to adjust something inside? Or could it be that I have to replace a chip, I only have a small cable for the antenna, but before that it was heard without problem, now nothing is heard, only the noise as if they were not broadcasting on radio stations.
I remember the commercials on these units. I looked at reviews and they wasn't completely favorable. Not the independent reviews. I never had one to try for myself. Do they blast the house down, or not?
Thank u for the video. I have bose wave radio AWRCC7 which is dead. I want to fix it myself. I need ur guidance. The amp portion of radio is not working. The microprocessor and the display is working good when I tested with the another amp of similar radio.(AWRCC7) . The only amp portion is need to be fixed. And when I tested with multimeter, I am getting voltage reading in the legs of ic tda7376b. But I could not locate the fuse in AWRCC7 pcb. I hope I can rectify with ur guidance. Thank u in advance.
I have a 3-2-1 gs and the speakers stopped playing but the unit still works through the tv. I have tested the speakers on another unit and they work. Any ideas?
@12voltvids can you post the part number for the amplifier? I have one with a similar issue, but no humming. I still have to test the voltage on the speakers...
good video but like many of us DIY people we come to watch because it is helpful. but like so many repair videos there is no information on where to get the parts. finding where to order the right parts is half the battle
Cool!... I have one of those Music System III sets sitting on top of my computer, my LCD monitor sitting on top of the Music System III, and the computer's sound card is connected to the AUX IN on the Bose.. awesome set. My boss gave me this one ... they are amazing sets .... it's so cool how Bose worked out the cabinetry in their products to increase the resonant airspace inside and make those little sets sound friggin' huge :-)
I was in the electronics repair profession years ago... back around the time that the first Bose table-top set came out, shaped like that one...little smaller..white cabinet.. they were amazing from the start. Kudos to Bose.
I just found one of these at a local thrift store for USD $6.99. Thank you Goodwill :) No remote though, so off to fleabay for that. It likely is a BTL amp which is basically two amp outputs driven out of phase connected to each terminal of a speaker. It's a common way of getting a good amount of power into a speaker from a low power supply voltage such as 12 volts, often used in car stereos. BTL is "bridged tied load". In a 12 volt system, there is about 6 volts DC on each of the speaker terminals, so you don't want to connect any of the speaker terminals to "ground".
A very comprehensive presentation. For the compact unit these wave radios are, it gives a very good sound, and no other manufacturer than 'Bose' makes them. I see the audio power IC is made by ST Microelectronics, and being for car radio applications, would be for some time available for replacement. According to data sheets, the 'bridge' configuration allows power output of 4 times that of one terminal speaker grounded, capacitor coupled, on older designs. Another feature is the very low noise (ripple rejection) from the power supply, as the amplifiers are identical, only driven anti-phase for the speaker - and speaker +.
Hello, great video. Do you have by any chance an idea of how could I repair AUX connector on my bose wave III ? Every thing is working perfectly expect this AUX connector. I disassemble the device but I didn't see any problem... Any ideas ? Thank you in advance !!!
Great repair brother. I'd be a bit weary of the desoldering work on such a board. I hate stubborn soldering. patience and a few solder tricks wins the day.
Make it yourself. Just stroke the screwdriver against a magnet. After a short while its magnetized. Funnily enough the problem is normally demagnetizing your tools.
I have a Bose wave my radio will not work with remote only few buttons work so I thought I had bad remote and I bought a new one from Amazon and still same thing please let me know..
That IC cost me only about 10.00 from Digikey. I have another identical system that just came in for service that I will be looking at real soon. It has a CD changer problem.
As from what I've learned from your other vids - wouldn't it be better to check the Caps as well before installing the the new chip - or would that be going to far, ?
i have a similar issue, when i power on the system, clock displays time correct, but when i try to turn on the radio it get (please wait flashing up a few times then goes back to the clock, if i select cd it does the same. (please wait) then nothing. could it be the power amplifier? possible you could suggest what could be the issue. thanks for your time
I have an early Bose wave AWR1 that takes 3 AA batteries in the bottom. Even though I put 3 new batteries in the radio they only last for about 4-5 days. Any suggestions on why it uses them up so fast???? Other than that it works fine. Suggestions????
Something that the batteries are tied into has developed high leakage. If you were to connect a multimeter set to read milliamps in series with one of the battery lines into the set, you will probably see a drain of a few ma. The current taken from such memory backup should be virtually zero. Unfortunately, tracking down the source of this drain will involve disconnecting one side of each component connected to the batteries and rechecking the current draw until you disconnect something that causes a big drop in the reading, probably a capacitor or an i.c. Do not overlook the possibility of corrosion on the p.c.b., which can create a leakage path producing this problem.
I was given a Bose wave 1 that didnt work. Opened it up and none of the components were kabeled. I caled Bose to get a schematic. The guy told me that theyee fix it for $99 turn key. Then he asked me to hold on please. He came back and asked me to read the serial number back again. So i did and he asked me to hold again. He told me that the radio i had was actually one of the first product runs and his manager wanted it that he would trade me for a new wave II. I said ok. With just my word that id mail it back to them, a few days later, sure enough a new wave II radio came in thevmail with a return label. Absolutely love my Bose.
Interesting. It would have been a USA made unit and he probably wanted it for that reason. Perhaps for a display, or advertising or perhaps the manager just wanted it for his collection and sending you a sample would just be a write off to get a classic and probably rare piece.
I like to use the solder wick type that already has rosin powder on it. The wicks without the rosin is useless. Nothing beats a decent electric desoldering pump, though.
Nice repair ,anyone no why I always see so many bose wave radios for sale on line.,like eBay and goodwill etc.Do they break a lot of something ,I no they cost a lot too?
My wave has been erratic..sometimes will belt out a very loud static type buzzing when radio is off...or better yet in the middle of the night...any suggestions?
My bose wave radio, ,about 10 years old is not playing sound after it fell on he floor. Initilaly, only the radio lost sound, then the cd lost sound also, everything else seems to work
I used to save the great base speakers from the Boombox radio whenever it has a bad shape plastic cabinet or it is not working anymore like for example my 2001 RCA Boombox radio RCD110B that are made in China, I do recycle them by save the spare parts and the speakers so that I can use the speakers as an external speakers by make a wood cabinet for example, to make a nice sound quality. Not to mentioned that JBL used to make a good quality speakers here two since it has a large magnet on the voice coil. I do love the products that are made in USA. =)
At the beginning of the video I'm sure I was thinking the exact same thing you were. A bad filter capacitor on the power supply. Then as soon as I saw that one channel pushing the sub outwards I'm sure we both thought the exact same thing. Guess great minds think alike..lol
+Ryan96se The DC on the speaker was a dead giveaway.This unit uses a bi-amplified output.For those unfamiliar with this, it is an old trick that started in the car radio industry.On a conventional amplifier, your negative speaker terminal is grounded. If your power supply uses a split 12 volt supply, with +12 and -12v, the swing on a class AB amplifier single ended output could be -12 to +12 v peak with respect to ground.With a bi amplified amplifier there are 2 amplifiers operating, one in running in inverted waveform. In other words as 1 amplifier is headed positive, the other one is heading negative with a mirror image signal.These 2 outputs are fed to the + and - speaker terminals respectively.Now you have a 24 volt swing, where the negative terminal is swinging down to -12 and the positive up to +12. Double the voltage, same current same power input. That almost doubles the wattage.It makes for relatively efficient amplifiers, be it at the expense of distortion, but it allows more power without having to use a higher voltage power supply. IN this case one of the outputs shorted to full DC voltage, but the other half of the output was still working, so that is why there was still audio present on that noisy channel.
My hum is only when an FM station comes in. No hum on the CD side. Do you know what component this might be, or where could I look at on the board for the problem?
That's a really cool fault. Now what's the proper way to test a short on an IC like this if you wanted to go about doing this? I read you're supposed to test continuity between the ground pin and the other pins and see if there are shorts, but idk if this is actually true.
Hello. I'm an amateur, currently working on one as per family request. The faulty unit produces loud intermittent pops and crackles. Sometimes there is speaker audio output (FM/AM, CD etc.), sometimes there isn't. Gently messing and wiggling wires, connectors or heatsink has no effect in forcing the problem. Have not checked 3.5mm OUT yet. I suspect it may be that TDA7376B, but given the current electronics availability (lead time of ±50weeks on the TDA7376B, for example), what would be a good starting point for further analysis and ruling things out? Visual checks indicate no blown caps, there appear to be no speaker wire faults and no faulty power chord. Bose repair is about 140$, where they most likely just replace the mainboard instead of repairing/replacing a (what is likely to be) cheap sub-$10 component. I have managed to find the large troubleshooting guide including lots of information and diagrams. Unfortunately it discusses the mk1, mk2 and mk3 in one document and not much can be found one the mk1 in terms of troubleshooting this particular issue. Thank you in advance.
Update: The unit has been tested on signal throughput. A 1K Ohm frequency was set on the AUX IN, and measured with an oscilloscope. Unfortunately, the signal was no longer detectable before it reached the HCF4052 chips. It is likely that there may be a fault in one of those. Or perhaps still the TDA7376B? Any thoughts?
Very right made in usa is rarely seen ....these things screams quality ...I got lot of music system build in 90s n2000 ...I really miss that quality...neatly put together...
I just recently bought a Bose Wave Music System for $85 ($50 + $35 shipping) on eBay. The only thing wrong with it is the CD player doesn't work but I love it.
Hello 12voltvids,my Bose Wave AWCRR3 is only working when it is warmed up. When I disconnect the radio from the power supply for 1 minute and turn it on again the radio goes on, I can see the clock and swich to menue, but I can't swich to FM/ AM, cd or AUX. When I warm it up, everything works fine. I very much hope that you have a solution for this problem.
Sure sounds like a cap that is going bad somewhere. You need an ESR meter to measure to find the one that is going bad as there will likely not be any physical indicators.
Some companies try to sell headphones for $50k haha bose highest is $400 hard to define overpriced in audio bose dont post wattage for a reason because most of the masses doesnt know 100 watt and a 1000 watt system can sound the exact same and have the same power its efficiency most people really in to audio would know a 100 watt system can smoke an inefficient 1000 watt system anyday
12voltvids I have the AW-1 which I believe is the original (much larger) Wave radio/cassette unit. Was wonderful for many years. The sound is now intermittent and intermittent between channels. For the most part the bass is non/existent UNTIL after warming up when there is a loud popping sound which sometimes means the output will be normal for a while. The cassette mechanical is fine but the output is the same as the radio output; temperamental. I would be interested in having it repaired = all Bose offered was a similar radio for 499. (!) They do not repair these anymore. 12voltvids Can you assist me in getting it repaired? TIA! Id send it to ya? Or?
+Gary Kimes I bet it is s similar problem, a power amp IC or perhaps a capacitor is failing.You can contact me via Email from my web page which is accessible from the main screen
pls what is the ic number for the power my Bose Wave Music System III is blow my son plug it into a 240v instead of 110v how do i repair it lost the ic after taken it out
You'l need the service manual and schematics to know that, and those aren't very easy to find. Also, if it was run on twice the voltage, likely there'll be a few other blown components as well.
Do you know if replacement speakers are available for these? I have one and it's 10 years old (owned it since new) and the right speaker sounds blown (has that "blown speaker sound"). I'd like to go ahead and do the repair if they sell the speaker.
+Vincent D I don't know if they have a replacement available but for sure you can get the speaker re-coned. I had that done to my pair of Altec Lansing speakers. Pretty much every big city has a speaker shop where they do nothing but recone speakers. Usually for musicians that blow them cranking their amplifier to 12!They can rewind the voice coil no problem. I dealt with a shop in Vancouver, and he gets speakers sent in from all over the place. Does lots for movie theatres where they blow their speakers all the time running sound tracks too loud. Showed me one where the cone actually caught fire they drove it so hard!
Very helpful, i had the same problem, i just recapped the board. It worked . But that amp was a FET amp, not an Amp IC like this one . But now I know what to do with my car radio
Most people won’t recone any speaker smaller than 8 or so inches. No parts are available. However, these drivers are common. They were also used in both the original and v2 sound dock. Bose cubes and companion 2 speakers never used the exact same drivers, but the drivers in those are actually the same size.
Hi 12voltvids , my parents brought down their BOSE WAVE MUSIC SYSTEM 3, ref: AWRCC3. Now it seems to have reader's concern CD. Indeed CD player have difficulty in being correctly read. Of what do you think that he can involve? The CD module can be replaced ? For my part, I unsettled the device to reset the position of the lens which seemed to be blocked. Thank you in advance for your help. Regard
+Densetsu ERAUSQUIN If the CD isn't being read it could be a couple of things. The spindle motor may be worn out of the optical pickup bad. If it was used in a smoking environment then the optical block internal optics could have smoke film accumulating on the optics and blocking the laser beam. Of course check the lens for dust.
Sure is a great video and helped me solve some problems while, as a novice, servicing mine. I wish though I could work out why I cannot adjust the display brightness levels using the remote. Anyone?
I only recently learnt this Wave radio/CD series has been discontinued only months ago, per Bose retail/showroom staff...... This is ridiculous. A great form of A/V hardware configuration that has served many for decades only to be deprecated in present day due to the shift in modern A/V lifestyle and such. Very, very sad indeed......
Have an old WAVE BOSE radio with buttons on the top! The remote does not have that little thingy on the left side to push. Trying to change battery, which has NEVER been changed.
TDAxxxxB, but you would have already known that if you watched it through. Notice I didn't tell you the number, as I hold the data sheet up in front of the camera and the part number is clear as day at 8:45
My Bose radio (AWRC-1G) turns off on it’s own when I’m listening to the radio or CD. The clock remains lit, albeit dimmed, and as soon as I press the PRESET buttons for my saved stations or the CD button, it immediately starts up again for an erratic period. May be 20 seconds or 20 minutes. Above also occurs when I’m CERTAIN all alarm settings are OFF. Any easy and affordable, DIY ideas? Thanks in advance!
Is this something I can repair/replace myself (if so where does one get the power supply?) or must I send it to BOSE? -- Thanks in advance for your wisdom.
Early in my career I was instructed by both other techs and in the classroom and alsobself taught. I have probably 100 course completion certificate from Sony Panasonic JVC nakamichi RCA Toshiba and Yamaha.
i have one of these radios, it wont turn on when plugging it in, but when i unplug it from the wall it makes a popping sound, any idea why this happens? Thanks

Great video! I was looking for a video of fixing bose wave as a reference to fix mine.
You helped me very much.
Thanks a lot.
Best clock radio I ever owned. Some Bose stuff may be over rated, but this radio unit is amazing and worth every penny.

I'm happy to see that I was wrong!
I was thinking since you could still hear music in the background, it wasn't the amplifier, possibly a capacitor in the power supply,? but then you showed the speaker popping out & wow that did not look right!
I got to learn something new again from you today Dave. thank you!

That's a filter cap right there in the middle back of unit, correct? Did you discharge it beforehand, or was it in the video and I just missed it?
Thanks for a great video. I just picked up a new Wave SoundTouch Music System IV, and can report this unit is now being "Made in Mexico". As this is their latest and greatest Wave Radio, it doesn't auger well for continued assembly in the U.S.A.
+smsstuart What a surprize! Just like everything else these days. I am sure the quality will show. I know the 321 system I serviced the subwoofer / power supply was made in Mexico, but the head end, that is the amplifier / DVD player was made in USA, but the actual DVD drive was from Taiwan, and that was where the problem was, a broken plastic gear. Blackberry used to make their phones in Canada, and finish them off in Mexico, but that too has now shifted to China.
Nice Video!
Sorry for my bad Englsih, I am from Germany.
I subscribt you.
How are you disconnecting and reconnecting the ribbons? It appears you just pull on them to disconnect
another great video. Question........ is there a source for the 21 conductor ribbon cable used on the older bose wave systems .?
I found a source online that makes made-to-order ribbon cables. Sorry, but I don't have a link. Made to width of ribbon and width between individual conductors and number of conductors.
This one has a 120Hz hum and a DC offset. I've got a Wave Radio in the shop that's got a 60Hz hum and no offset, and no audio gets through. Where did you get schematics and parts?
Hi, I have a lifestyle 5 model 614810, everything works perfectly, but
little by little did you lose the tuning of the radio? Will I have to
adjust something inside? Or could it be that I have to replace a chip, I
only have a small cable for the antenna, but before that it was heard
without problem, now nothing is heard, only the noise as if they were
not broadcasting on radio stations.
I remember the commercials on these units. I looked at reviews and they wasn't completely favorable. Not the independent reviews. I never had one to try for myself. Do they blast the house down, or not?
Thank u for the video. I have bose wave radio AWRCC7 which is dead. I want to fix it myself. I need ur guidance. The amp portion of radio is not working. The microprocessor and the display is working good when I tested with the another amp of similar radio.(AWRCC7) . The only amp portion is need to be fixed. And when I tested with multimeter, I am getting voltage reading in the legs of ic tda7376b. But I could not locate the fuse in AWRCC7 pcb. I hope I can rectify with ur guidance. Thank u in advance.
I have a 3-2-1 gs and the speakers stopped playing but the unit still works through the tv. I have tested the speakers on another unit and they work. Any ideas?
@12voltvids can you post the part number for the amplifier? I have one with a similar issue, but no humming. I still have to test the voltage on the speakers...
I have the same exact wave system built in the good ol' U.S. of A...Brand new, everything works except it has no sound. Any idea on what may be wrong?
good video but like many of us DIY people we come to watch because it is helpful. but like so many repair videos there is no information on where to get the parts. finding where to order the right parts is half the battle
Cool!... I have one of those Music System III sets sitting on top of my computer, my LCD monitor sitting on top of the Music System III, and the computer's sound card is connected to the AUX IN on the Bose.. awesome set. My boss gave me this one ... they are amazing sets .... it's so cool how Bose worked out the cabinetry in their products to increase the resonant airspace inside and make those little sets sound friggin' huge :-)
I was in the electronics repair profession years ago... back around the time that the first Bose table-top set came out, shaped like that one...little smaller..white cabinet.. they were amazing from the start. Kudos to Bose.
thanks. not my problem, mine wont read cd's, but definite thanks for the follow-up video on the 3 disc changer that won't start when I insert discs.
I just found one of these at a local thrift store for USD $6.99. Thank you Goodwill :) No remote though, so off to fleabay for that. It likely is a BTL amp which is basically two amp outputs driven out of phase connected to each terminal of a speaker. It's a common way of getting a good amount of power into a speaker from a low power supply voltage such as 12 volts, often used in car stereos. BTL is "bridged tied load". In a 12 volt system, there is about 6 volts DC on each of the speaker terminals, so you don't want to connect any of the speaker terminals to "ground".
A very comprehensive presentation. For the compact unit these wave radios are, it gives a very good sound, and no other manufacturer than 'Bose' makes them. I see the audio power IC is made by ST Microelectronics, and being for car radio applications, would be for some time available for replacement. According to data sheets, the 'bridge' configuration allows power output of 4 times that of one terminal speaker grounded, capacitor coupled, on older designs. Another feature is the very low noise (ripple rejection) from the power supply, as the amplifiers are identical, only driven anti-phase for the speaker - and speaker +.
Tymphany makes good fullranges

Good job man, love it, the only thing missing was the IC number, maybe a TDA7294...thanks for the tutorial ;)
+chickenwatt check at 8:47 It is a TDA7376B, complete with the data sheet.
Hello, great video. Do you have by any chance an idea of how could I repair AUX connector on my bose wave III ?
Every thing is working perfectly expect this AUX connector. I disassemble the device but I didn't see any problem... Any ideas ? Thank you in advance !!!
I have the same issue with my awrcch model :(
i have a pair of BOSE 701, my little son dropped his toys inside, how can I get the toys out
Great repair brother. I'd be a bit weary of the desoldering work on such a board. I hate stubborn soldering. patience and a few solder tricks wins the day.
I just had the same problem on my wife's Bose Wave. Same issue. Can you let me know where you bought the part required? Thank you.
Do you use screwdrivers with magnetic tips for holding the screws? If so, who makes them? Thanks.
Make it yourself. Just stroke the screwdriver against a magnet. After a short while its magnetized. Funnily enough the problem is normally demagnetizing your tools.
I have a Bose wave my radio will not work with remote only few buttons work so I thought I had bad remote and I bought a new one from Amazon and still same thing please let me know..
How much did the replacement part cost ,Bose are exspensive ,always were ,but they make good stuff ,I would love to have that system.,good video
That IC cost me only about 10.00 from Digikey.
I have another identical system that just came in for service that I will be looking at real soon. It has a CD changer problem.
As from what I've learned from your other vids - wouldn't it be better to check the Caps as well before installing the the new chip - or would that be going to far, ?
Caps won't take out the chip
I have one and it powers up but will not play music from radio or CD's any ideas what it could be? Or can I send it to you for repairs?
i did replaced the ic but the sound is still bad with noise in speakers
Good job!
Hi i have changed all the capacitors and Also the TDA component but i have the same issue from the speakers..any solution?
i have a similar issue, when i power on the system, clock displays time correct, but when i try to turn on the radio it get (please wait flashing up a few times then goes back to the clock, if i select cd it does the same. (please wait) then nothing.
could it be the power amplifier? possible you could suggest what could be the issue.
thanks for your time
wayne T -I have exactly the same problem. did you ,answer to solve your issue?
did you ever get an answer?
I have an early Bose wave AWR1 that takes 3 AA batteries in the bottom. Even though I put 3 new batteries in the radio they only last for about 4-5 days. Any suggestions on why it uses them up so fast???? Other than that it works fine. Suggestions????
Something that the batteries are tied into has developed high leakage. If you were to connect a multimeter set to read milliamps in series with one of the battery lines into the set, you will probably see a drain of a few ma. The current taken from such memory backup should be virtually zero. Unfortunately, tracking down the source of this drain will involve disconnecting one side of each component connected to the batteries and rechecking the current draw until you disconnect something that causes a big drop in the reading, probably a capacitor or an i.c. Do not overlook the possibility of corrosion on the p.c.b., which can create a leakage path producing this problem.
I was given a Bose wave 1 that didnt work. Opened it up and none of the components were kabeled. I caled Bose to get a schematic. The guy told me that theyee fix it for $99 turn key. Then he asked me to hold on please. He came back and asked me to read the serial number back again. So i did and he asked me to hold again. He told me that the radio i had was actually one of the first product runs and his manager wanted it that he would trade me for a new wave II. I said ok. With just my word that id mail it back to them, a few days later, sure enough a new wave II radio came in thevmail with a return label. Absolutely love my Bose.
Interesting. It would have been a USA made unit and he probably wanted it for that reason. Perhaps for a display, or advertising or perhaps the manager just wanted it for his collection and sending you a sample would just be a write off to get a classic and probably rare piece.
What if it makes no sound?
I like to use the solder wick type that already has rosin powder on it. The wicks without the rosin is useless. Nothing beats a decent electric desoldering pump, though.
This does have rosin in it. All brain does or it wouldn't work.
What about ESD?
thanks for sharing...
Nice repair ,anyone no why I always see so many bose wave radios for sale on line.,like eBay and goodwill etc.Do they break a lot of something ,I no they cost a lot too?
My wave has been erratic..sometimes will belt out a very loud static type buzzing when radio is off...or better yet in the middle of the night...any suggestions?
That seems to match up with an unstable power supply causing the control electronics to mess up.
My bose wave radio, ,about 10 years old is not playing sound after it fell on he floor. Initilaly, only the radio lost sound, then the cd lost sound also, everything else seems to work
I used to save the great base speakers from the Boombox radio whenever it has a bad shape plastic cabinet or it is not working anymore like for example my 2001 RCA Boombox radio RCD110B that are made in China, I do recycle them by save the spare parts and the speakers so that I can use the speakers as an external speakers by make a wood cabinet for example, to make a nice sound quality.
Not to mentioned that JBL used to make a good quality speakers here two since it has a large magnet on the voice coil.
I do love the products that are made in USA. =)
Awesome 👍 job great work.thank for sharing.Just saying.
At the beginning of the video I'm sure I was thinking the exact same thing you were. A bad filter capacitor on the power supply. Then as soon as I saw that one channel pushing the sub outwards I'm sure we both thought the exact same thing. Guess great minds think alike..lol
+Ryan96se The DC on the speaker was a dead giveaway.This unit uses a bi-amplified output.For those unfamiliar with this, it is an old trick that started in the car radio industry.On a conventional amplifier, your negative speaker terminal is grounded. If your power supply uses a split 12 volt supply, with +12 and -12v, the swing on a class AB amplifier single ended output could be -12 to +12 v peak with respect to ground.With a bi amplified amplifier there are 2 amplifiers operating, one in running in inverted waveform. In other words as 1 amplifier is headed positive, the other one is heading negative with a mirror image signal.These 2 outputs are fed to the + and - speaker terminals respectively.Now you have a 24 volt swing, where the negative terminal is swinging down to -12 and the positive up to +12. Double the voltage, same current same power input. That almost doubles the wattage.It makes for relatively efficient amplifiers, be it at the expense of distortion, but it allows more power without having to use a higher voltage power supply. IN this case one of the outputs shorted to full DC voltage, but the other half of the output was still working, so that is why there was still audio present on that noisy channel.
My hum is only when an FM station comes in. No hum on the CD side. Do you know what component this might be, or where could I look at on the board for the problem?
That's a really cool fault. Now what's the proper way to test a short on an IC like this if you wanted to go about doing this? I read you're supposed to test continuity between the ground pin and the other pins and see if there are shorts, but idk if this is actually true.
Hello. I'm an amateur, currently working on one as per family request. The faulty unit produces loud intermittent pops and crackles. Sometimes there is speaker audio output (FM/AM, CD etc.), sometimes there isn't. Gently messing and wiggling wires, connectors or heatsink has no effect in forcing the problem. Have not checked 3.5mm OUT yet. I suspect it may be that TDA7376B, but given the current electronics availability (lead time of ±50weeks on the TDA7376B, for example), what would be a good starting point for further analysis and ruling things out? Visual checks indicate no blown caps, there appear to be no speaker wire faults and no faulty power chord. Bose repair is about 140$, where they most likely just replace the mainboard instead of repairing/replacing a (what is likely to be) cheap sub-$10 component.
I have managed to find the large troubleshooting guide including lots of information and diagrams. Unfortunately it discusses the mk1, mk2 and mk3 in one document and not much can be found one the mk1 in terms of troubleshooting this particular issue.
Thank you in advance.
Update: The unit has been tested on signal throughput. A 1K Ohm frequency was set on the AUX IN, and measured with an oscilloscope. Unfortunately, the signal was no longer detectable before it reached the HCF4052 chips. It is likely that there may be a fault in one of those. Or perhaps still the TDA7376B? Any thoughts?
Update: replacing the TDA7376B did not solve the issue. The device boots up properly and all input types work, just no sound coming out.
Very right made in usa is rarely seen ....these things screams quality ...I got lot of music system build in 90s n2000 ...I really miss that quality...neatly put together...
I just recently bought a Bose Wave Music System for $85 ($50 + $35 shipping) on eBay. The only thing wrong with it is the CD player doesn't work but I love it.
Hello 12voltvids,my Bose Wave AWCRR3 is only working when it is warmed up. When I disconnect the radio from the power supply for 1 minute and turn it on again the radio goes on, I can see the clock and swich to menue, but I can't swich to FM/ AM, cd or AUX. When I warm it up, everything works fine. I very much hope that you have a solution for this problem.
Sure sounds like a cap that is going bad somewhere. You need an ESR meter to measure to find the one that is going bad as there will likely not be any physical indicators.
The speakers are of the shielded variety i.e. inverted magnet glued to back pole the metal cup to "contain" the field.
heh
I've had mine 19 years, it's still perfect. Is it overpriced? I think not.
Some companies try to sell headphones for $50k haha bose highest is $400 hard to define overpriced in audio bose dont post wattage for a reason because most of the masses doesnt know 100 watt and a 1000 watt system can sound the exact same and have the same power its efficiency most people really in to audio would know a 100 watt system can smoke an inefficient 1000 watt system anyday
12voltvids I have the AW-1 which I believe is the original (much larger) Wave radio/cassette unit. Was wonderful for many years.
The sound is now intermittent and intermittent between channels. For the most part the bass is non/existent UNTIL after warming up when there is a loud popping sound which sometimes means the output will be normal for a while.
The cassette mechanical is fine but the output is the same as the radio output; temperamental. I would be interested in having it repaired = all Bose offered was a similar radio for 499. (!) They do not repair these anymore.
12voltvids Can you assist me in getting it repaired? TIA! Id send it to ya? Or?
+Gary Kimes I bet it is s similar problem, a power amp IC or perhaps a capacitor is failing.You can contact me via Email from my web page which is accessible from the main screen
what is the name of the CD? can you post a picture of it too?
The CD is the Boston Pops, don't know the title though. It was in the unit when it came in for service, and this is back with it's owner now.
pls what is the ic number for the power my Bose Wave Music System III is blow my son plug it into a 240v instead of 110v how do i repair it lost the ic after taken it out
You'l need the service manual and schematics to know that, and those aren't very easy to find.
Also, if it was run on twice the voltage, likely there'll be a few other blown components as well.
Seen these in magazines alot
Do you know if replacement speakers are available for these? I have one and it's 10 years old (owned it since new) and the right speaker sounds blown (has that "blown speaker sound"). I'd like to go ahead and do the repair if they sell the speaker.
+Vincent D I don't know if they have a replacement available but for sure you can get the speaker re-coned. I had that done to my pair of Altec Lansing speakers. Pretty much every big city has a speaker shop where they do nothing but recone speakers. Usually for musicians that blow them cranking their amplifier to 12!They can rewind the voice coil no problem. I dealt with a shop in Vancouver, and he gets speakers sent in from all over the place. Does lots for movie theatres where they blow their speakers all the time running sound tracks too loud. Showed me one where the cone actually caught fire they drove it so hard!
Very helpful, i had the same problem, i just recapped the board. It worked . But that amp was a FET amp, not an Amp IC like this one . But now I know what to do with my car radio
Most people won’t recone any speaker smaller than 8 or so inches. No parts are available. However, these drivers are common. They were also used in both the original and v2 sound dock. Bose cubes and companion 2 speakers never used the exact same drivers, but the drivers in those are actually the same size.
Hi 12voltvids , my parents brought down their BOSE WAVE MUSIC SYSTEM 3, ref: AWRCC3. Now it seems to have reader's concern CD. Indeed CD player have difficulty in being correctly read.
Of what do you think that he can involve? The CD module can be replaced ?
For my part, I unsettled the device to reset the position of the lens which seemed to be blocked.
Thank you in advance for your help.
Regard
+Densetsu ERAUSQUIN If the CD isn't being read it could be a couple of things. The spindle motor may be worn out of the optical pickup bad. If it was used in a smoking environment then the optical block internal optics could have smoke film accumulating on the optics and blocking the laser beam. Of course check the lens for dust.
+12voltvids Thx. i will check that when i have some time and come back for tell you what happen ^^
Sure is a great video and helped me solve some problems while, as a novice, servicing mine. I wish though I could work out why I cannot adjust the display brightness levels using the remote. Anyone?
I only recently learnt this Wave radio/CD series has been discontinued only months ago, per Bose retail/showroom staff......
This is ridiculous. A great form of A/V hardware configuration that has served many for decades only to be deprecated in present day due to the shift in modern A/V lifestyle and such. Very, very sad indeed......
just got one from 1994... think it is the first model ... same problem... voltage on the amp... so I had to order one ... now the wait begins...
great great job
Sir my bose wave speaker no connection to Bluetooth end auxiliary en cd
Where is the inline fuse located? Our Bose AWRCC2 won’t turn on at all. Hoping it is the inline fuse...
I have no idea. I have only worked on about 5 of those units ever.
I usually cut all the leads on complex components like these and remove them one at a time. Saves time and is much less destructive.
Wish you would repair my Bose Amplifier it's a PS18/48, I'm sure it's an easy repair for someone that know electronics.
what the part number and name?
I ha e one of those and stop working just turn on the screen but nothing hear
Have an old WAVE BOSE radio with buttons on the top! The remote does not have that little thingy on the left side to push. Trying to change battery, which has NEVER been changed.
You squeeze the tab and the battery tray slides out.
Have same issues with CD player
something about these Bose waves, interesting to see whats inside.
Dear 12voltvid let us know the ic number {which is replaced}
Thanks
TDAxxxxB, but you would have already known that if you watched it through.
Notice I didn't tell you the number, as I hold the data sheet up in front of the camera and the part number is clear as day at 8:45
My Bose radio (AWRC-1G) turns off on it’s own when I’m listening to the radio or CD.
The clock remains lit, albeit dimmed, and as soon as I press the PRESET buttons for my saved stations or the CD button, it immediately starts up again for an erratic period. May be 20 seconds or 20 minutes.
Above also occurs when I’m CERTAIN all alarm settings are OFF.
Any easy and affordable, DIY ideas?
Thanks in advance!
Sounds like a power supply issue or partial short of some kind.
Is this something I can repair/replace myself (if so where does one get the power supply?) or must I send it to BOSE? -- Thanks in advance for your wisdom.
I have a Bose wave with static in left side even with the volume all the way down. Already checked all the capacitors. Any ideas?
Probably the amp ic as in this one.
OK that’s what I thought when I came upon your video just wanted to make sure
How do you learn this type of work? Are you self taught or instructed?
Early in my career I was instructed by both other techs and in the classroom and alsobself taught. I have probably 100 course completion certificate from Sony Panasonic JVC nakamichi RCA Toshiba and Yamaha.
i have one of these radios, it wont turn on when plugging it in, but when i unplug it from the wall it makes a popping sound, any idea why this happens? Thanks
+Dink Worm actually i have the old bose wave radio, its from the 90s
That sounds like a amplifier or power supply problem. Is it version 1993, 1994, or 1996?
I can provide service manuals if you would like them.
