Can't believe you found that lovely JVC cd player at the side of the road covered in mud, all I find at the side of the road is mud. Maybe I'm looking in the wrong place
Hands down the Akai one is the most interesting
I will look forward to you taking them apart. I fancy the Pioneer Cassette deck first.
Akai and Onkyo next.
Love 80's/90's audio gear !!! Made in Japan quality.
"The Motor is bad"
-Hold my beer!
It seems like these Philips mechanisms really like those Andrea Berg CDs
The Akai is my favourite !!
Nice haul. That Akai is a sexy machine.
The AKAI!
Nice vid. I really liked the looks of the Akai deck, looks like quality.
Something about those old JVC CD players that keeps them going. I have a JVC XL-V211 single disk player from 1989 that still works like new. It works better than any CD player past or present. It's lasted longer than Sony's and Pioneer's I have had since that time.
Some nice cassette decks here: three of them with 3 heads, which usually denotes a high quality deck.
CT-S550S is a good deck, >20khz range >80db S/N. It needs to be switched off by cable to save display
The Sony CDP-710 is from 1987. Most of the early laser mechanisms from Sony have issues reading CDR, which appears to be your test disc. You may want to try testing the unit with a manufactured CD.
Actually the Sony CD player will play CD-Rs after I cleaned the laser. I use good quality CD-Rs and I burn them at relatively low speed, so they are about as good as regular CDs. If a CD player does not play CD-Rs at all it is pretty worthless to me.
the Akai is so beautiful!
Telefunken first!
I once found a Telefunken HC700 in the dumpster. Worked fine, but only got like 5 Euros on eBay even though it had HighCom.
Both decks look surprisingly similar.
First time you look at it and think wow, but after looking at it for more than five minutes you can't stand it any more because there's just nothing to look at!
I have a Mitsubishi VCR from 1984 with linear stereo(!) where the VFD is also so dim you can only read it in total darkness.
Very juicy stuff love those old players look forward to your restoration videos.
Slightly unrelated, but yesterday my brother found an Akai HX-1 cassette deck on the side of the road, and it works, at least playback works, I was very much reminded of the videos you do as I was testing it.
The Akai HX-1 looks like a nice cassette deck :)
5:00 i love these JVC cd players, very high quality laser mechanism, much better than Sony and other brands.
My local hifi dealer used to recommend Technics CD players in the late 1980s for budget customers. They had the reliable (though I don't think all that good, see my other post) Philips mechanism, but the lower-end players had Panasonic DACs which to their ears sounded better than the TDA1543 which went into the cheaper Philips units and tended to have a high noise floor. Also Matsushita build quality generally was always pound-for-pound better than Philips.
There are some components worth saving in that collection. The Pioneer CT-S models were actually pretty decent decks. The Onkyo deck looks decent as well. The AKAI looks good, too. At least, you don't have to worry about head wear on a GX machine.
Why no wear? Is it ceramic / glass?
@@VioletGiraffe The GX head was a glass/ferrite combination. Very resilient against wear, but not as good-sounding as the later amorphous heads.
Dr. Cassette you do always incredible work thank you for your work and sharing the often difficult and complex repairs which you do with ease, On this particular video I would like to see the repair procedure on the Akai machine for me the nicer of all thank you keep up the great work 🎥⭐⭐⭐⭐⭐🎼
As I said in the video, I probably won't be able to make a video of the Akai GX-6 repair. It seems like it will be a complex process requiring full concentration. And I can't fully concentrate when I also try to make a video at the same time.
Very nice technics, Simple but really good
I see akai cassettedeck, watch out if you have to change the belt for the door, the camreel must be in correct way, or the door don't open close like it should 👍
I still have my Technics SL-P202A which I've purchased from new in 1989.
It still works well and these machines can also operate with remote control.
I use 4 in 1 universal remote and I can go straight to any track I want.
I don't understand why Technics supply them without remotes.
Back then it was quite common that the amplifier would come with a system remote control. The simple systems then used additional data cables to connect all components to the amplifier which would send out the commands from the system remote control via these cables. But there was also a different approach, the amplifier would come with the system remote control, but all components had their own infrared receiver so that no additional cables were required. That probably was how this Technics CD player was supposed to be remote controlled.
I found a Technics SL-P555 for $10 at Pawn shop with remote and it works flawlessly. I've been using it for years.
Philips once made some very good CD players.
Made? Yes, invented them even...
Isn't it Amazing the things people throw away? What's even more hilarious is the average person traded quality Hi Fi equipment for the "new" junk of today that doesn't even come close. Bless em though. 🙏 it's more for us.
I liked the Pioneer and Akai tape decks...makes no difference which one to work on first, I enjoy your videos regardless. ~Jack, VEG
It is always nice when you upload a video!
Thanks for testing all those units. I need to make a video of my growing collection. I just a Denon DN-T620 a couple days ago.
I like the Pioneer, and it has Dolby S..although unfortunately I fear this example may have seen better days (worn heads and VFD). I love how you had to fight with it to load the cassette! The Akai also looks like a very nice looking deck.
Indeed the Pioneer has seen better days... after making the video I noticed the finish of the top cover is uneven like there was rust underneath. I will have to see what the inside of the deck looks like. If it is as bad as the outside, I don't think the Pioneer can be repaired economically.
Always been a fan of high end Akai gx decks from thas time period, hope the complicated rep. can be done - Onkyo tuner is very nice too, tuners like that really shows us how good FM transmissions can sound - so much better than low bitrate DAB crap.
Oh yes, DAB is terrible. Heavily compressed, and the reception is always bad. I briefly had a DAB radio when I was living in an apartment tower in Hannover. From the tower I had direct line of sight to the radio tower where the DAB transmitter is. There were only two walls between the radio tower and the radio antenna. Still, the signal kept cutting out every few seconds.
Akai looks to be the best of the bunch
I own that Technics tape deck and it had the same clicking noise. Never could fix it. I gave it way when I bought the Yamaha KX-380 cassette deck.
It turns out the Technics dual cassette deck does have the infamous soft plastic gears in the mechanism that like to loose their teeth. In my Technics however the teeth were all still intact, instead the soft plastic had gone super soft, so instead of engaging properly, the gear in the record mechanism would just bend out of the way causing intermittent operation.
the Telefunken is my favorite!
7:40 that's the CD player I had as a kid growing up. My mom gave me her old hi-fi system as a gift when she upgraded hers. Man I haven't see one of those in like 20 something years!
I have that Philips CD600 player. It's got a great sounding DAC in my humble opinion! Plus the laser mechanism is legendary in quality!
In my main stereo system I have a Philips CD618 which is similar to the CD600. Sounds better than the Sony CD player it replaced :)
@@DrCassette I also have a CD600; it's just a stellar performer. I have successfully replaced the loading gear and belt; loads available on ebay.
Best way to spray fluid glue from old belts. Never try to turn on old tape deck before checking what happened to belts
I know this can happen, but for the fun of making this video, I am taking the risk :)
@@DrCassetteP.s.) Pioneer's CT-S550 power switch is fake. Its only function is to tell processor to dim a red lamp and to stop providing info to VFD. VFD is on 24h/365days/years. Saved 50cents...
@@DrCassette I have gears for those panasonic rx models were they crack and it works quite well someone did 3d print them for me. I used it to save a high end boombox I have works great now. I even have 3 extraI think
I like the tuner honestly. That sort of model would work great here considering all the radio stations that are crammed in. It's too bad the Akai gave up the ghost, but I'm sure you'll have that sorted. Quite a nice haul of items.
The 3 cd players are a win,,,and u had found one in mud on the side of the road? Which still works as it should? Sounds like u had scored a few free items in perfect working condition.
I would repair the stereo cassette deck that was 2nd last in the video,,,along with the other few high quality stereo cassette decks too. Especially with the motorised eject cassette door. I have a few stereo cassette deck models,,,but u have to eject the tape manually on all of them.
I have the Onkyo T4250 tuner. 1986. Same features.. a model for German market. Native 220volts. Just different array of buttons.
My tuner was sold on the German market too ;)
@@DrCassette I make this precision because I foudn information of manufacturing differences for US market
The Pioneer was probably the highest quality device there when new. Would be great if you could get it running again.
Actually both the Onkyo and the Akai are better than the Pioneer. They have a dual capstan mechanism, the Akai even has direct drive. The only special feature of the Pioneer is Dolby S.
@@DrCassette Well it’s a 3 head deck too, isn’t it? I’m surprised it’s not dual capstan tho - most 3 head decks were. Dolby S was pretty killer. Pity about the display. I wonder if anything can be done about that.
@@sunspot42 Yes, of course. They are all 3 head cassette decks.
I have the Technics SL P310 with the foam padding on the tray, its a great CD player
Yep same issue here in the Netherlands - basically no AM stations anymore.
Some time ago, I considered making a foxhole radio, but without any AM stations it's pretty useless.
At 12:46 the "Hah!" made me lol!
Interesting selection of gear, I like to see the Philips CD 600 player opened up, as I have a very similar model (CD630) bought in 1990, still works perfectly, even the remote still works, never had the cover off the player, this model was also rebadged for Marantz too.
Interesting about the tuner, how long ago did your AM stations get shut down? Here in the UK we still have alot of stations on the AM band.
The last German station on mediumwave was the Deutschlandfunk. It ended transmission on the 31st of December, 2015. But even before, AM was pretty much irrelevant here in Germany.
☹️ - unfortunate for those who have analog/digital interfaced-analog radios/receivers/tuners
Nice catch. The Akai gx-6 and the Pioneer ct-s550s are both very nice when they work.
Very strangely addictive! I wonder how many of these will end up working properly.
The chances are pretty good that all of them will work properly. So far only the Technics dual cassette deck was a loss due to bad gears.
Akai, but you already suggested that this repair will be done w/out camera..btw..ireally enjoy this format..it is interesting to see the variety and old tech..i also liked the Integra...great video Doc..
Thank you :)
Nice, it is always fun to mess and test newly acquired stuff
Der Tuner ist cool, erinnert mich an meine eigenen Zeiten als Wellenjäger. Ein T9990 wäre genial gewesen! :) Ich hab mit viel Glück mal einen Grundig FineArts T9000 RDS Vorführer günstig bei einem Räumungsverkauf ergattert (500,- statt 1.800,- Mark Neupreis), leider hat der die letzten Jahre bei mir nur noch herumgestanden und dann irgendwann keinen Ton mehr von sich gegeben, ist in Sammlerhände gegangen. Tolles Gerät, mehr Ausstattung ging kaum und beim Inenleben ist einem das Herz aufgegangen, der war bis zum letzten Quadratzentimeter mit Elektronik vollgestopft.
Aufwändige Tuner sind immer etwas Feines. In vielen einfachen Geräten ist ja kaum etwas drin, das ist traurig. Leider muss man heute hörenswerte Radioprogramme schon sehr suchen, bei den Öffentlich-Rechtlichen gibt es aber Abends noch ein paar gute Musikprogramme. Bei Tunern habe ich immer gerne RDS, damit ich sofort weiß, welchen Sender ich eingestellt habe. Das hat der Onkyo natürlich leider noch nicht. Aber sonst ein sehr schönes Gerät. Interessant ist auch immer, einen guten Tuner mit meiner guten Dachantenne (Ringdipol) zu verbinden und zu schauen, welche Sender man damit bekommt. Da freue ich mich immer, wenn ich hier im tiefsten NDR-Sendegebiet auch WDR, HR und Radio Bremen bekomme. MDR ist keine Herausforderung, denn die strahlen für die Leute, die zum Arbeiten in den "Westen" pendeln, auch weit nach Niedersachsen rein. MDR Jump empfange ich hier besser als Njoy vom NDR! :P
@@ralfstocker7742 Ich weiß nur, daß der T9009 dem T9000 eine Fernbedienung voraus hatte, ansonsten waren sie augenscheinlich identisch.
Fascinating! Always interesting to see how old stuff works out. I cannot believe that someone left a fully functional CD player by the side of the road! Also amazing (to me) is your comment that Germany has no remaining AM radio stations. Here in Australia, many of the popular stations are still on AM and we are now just starting to see DAB+ radios in 'premium' models of cars. SIGH. Four years ago I traded in an old car with an upgraded after-market DAB+/CD radio, for a new car which ONLY had AM/FM radio! Great in every OTHER respect, but now I have to use my iPhone to receive digital radio stations, most of which I prefer, even for short trips to the local shops. Australia is so backwards in adopting new technology. Sometimes this helps a little (like DAB+ versus DAB) but mostly it just means we wait YEARS behind everyone else. ( EG: PAL colour TV in 1975, versus Europe in 1967.) The only advantage is that any technical issues have long since been sorted out.
That pioneer looks interesting.
I would like to see the Technics twin cassette deck working, and testing the quality of the dubbing from one cassette to the other.
Thanks.
Excellent agility at 12:44, and got me laughing :):)
That Pioneer does not want your tape hehe
I do want to see one of the CD players repaired because I want to see if they can be. If it was a tape deck though I would like to see the akai.
Always enjoyable to tinker with some old hifi!
The Akai GX-6 is a beautiful and very good deck.
I own a GX-8 also beautiful.
I love the JVC CD player & Philips CD Player
12.45 quick loading mechanism😁
Very quick indeed :D
@@DrCassette I wouldn't even try fixing that cassette door,I would leave it as it is. It makes me laugh every time I see It,just watch your fingers don't get caught in it.
Holy cow that is a lot of cassette players
The pioneer could have a fault in the power supply that supplies the vfd although I believe that many of the pioneer kit by this time left the vfd powered all the time even when in standby so although it looked like it was off it was still on and could see the filament wires glowing in a dark room.
I removed the colour filter in front of the VFD, it turns out the VFD works fine (including the Display Off function which only works in playback mode), but the VFD is very badly worn out. The heater voltage is 4.7 V which I think should be fine. The deck must have been turned on non stop for many years. The circuit board surrounding the voltage regulators is baked, and the inside of the top cover has turned black above the heat sinks.
I have the same Pioneer ct550S which has a slightly dim display, it has been refurbished. I will be very interested in seeing you work on that one.
I also have the ct550s and this self closing door problem. Would be nice to see a fix on that.
I had a look this summer at a couple of Sony CD players from that era, they had KSS-240A pickups and neither worked well at all, even despite a full cleaning and degrease of the sled and cleaning of the optics. Performance on CD-Rs was noticeable more intermittent than industrially produced music CDs. Maybe tweaking the laser output would have some effect, who knows.
I have heard about KSS-240A before, those are some of the laser assemblies in which the laser diodes tend to go bad. There are replacement assemblies available on Ebay.
If memory serves, KSS-240A contains a small SMD electrolytic capacitor that has a tendency to go bad. Seems worth a try. Remove old part, thoroughly clean board in case it leaked, install new one.
Also I am under the impression that lasers are rather more durable than one might think, and issues in that area is just as likely to be a bad detector diode.
Interesting line up there DC!
I must say - I really don't like auto-loaders, more to go wrong in my opinion.
And that Pioneer looks familiar, I once had a similar (or same?) model in the late 1990s.
I am currently working my way through a Sony TC-K45, but the repairs costs (and lots of time) have made it not-so-cheap!
All vintage sounds great! Akai gx 6 in first place.
do the telefunken first please
This clicking noise on Technics deck is made by broke sprocket - common fault of these mechanism. You can find new sprockets on eBay.
I will like to see first the repair for Pioneer CT-550S. I have one like this. Mine was hit on the left side next to the display (there are scratch marks on plastic) and now it has imperfect contact at display. If i bump it in that area the display will start working, also the brightness of the display is not constant, from nearly invisible to full brightness. When the display is off, all the buttons will stop working and some times i can hear the mechanism searching for the presence of the tape.
When you record with this deck, you need to auto calibrate de Bias by pushing BLE XD button, this is why your record sound bad. Also when you record with this model, keep in mind that he don't have the second Dolby S circuit for monitoring the tape. It will monitor the tape with Dolby B when you record with Dolby S, so it will sound bad on monitor. On play back is fine with Dolby S
Have you looked inside your deck and checked for any bad solder joints or cracks in the display circuit board? That might be the reason for these problems.
The recording didn't sound bad just because I hadn't used BLE XD. It was extremely muffled and there was almost no signal at all recorded on the right channel. This was due to dirt on the record head that was still on there even after cleaning. So the BLE XD system would not have helped.
I already read that there is no Dolby S for tape monitoring. I guess that's a clever way to create a relatively cheap cassette deck with Dolby S... the next model up the line had four Dolby S circuits, so tape monitoring worked as it should. Aside from that, it was identical to the CT-S550S.
@@DrCassette I change the caps form power source because i believe that was the problem. After that i realize that is a bad joint. I will open it again when i will have some free time
I would go for the akai!!!!
Regarding the CD's ... Philps vs Sony 2:0 ;). CDM-4 pickup's are quire reliable and last very long time, while Sony KSS's have problems after 20+ years. Luckily there is plenty of cheap chinese replicas you can try. The Philips CD 600 is using the TDA1543 that is a simplified and cheaper version of the TDA1541; the TDA1543 was very popular at the time in low to mid range devices due to its size (8 pin DIL) and low cost. Sony too used the TDA1543 in some of its smaller CD players.
Thanks for the info! Luckily the Sony CD player just needed the laser cleaned, it now works again. Funny thing is, the Sony contains the TDA1541 DA converter chip.
@@DrCassette The ideal CD player in that case - the TDA1471 coupled to an easily-replaceable laser. I've never been all that convinced of the quality of those CDM4 mechs. If you run a digital output from many of them it quickly becomes clear that the digital stream being read is riddled with errors, whereas the Japanese outputs tend to be much cleaner. So while the CDM4 lasts, I think they're actually pretty crappy.
@@jasejj the Japanese three beams pickup's are more susceptible to skip because they scan a wider area on the Disc and are affected by scratches or dirt out of data spiral groove. Single beam pick-up's are less susceptible to skipping unless the data stream on disc is heavily compromised. As for data error, CD has data redundancy and a very early version of FEC (Forward error correction); any error up to a certain BER (Bit Error Rate) is corrected with no effect on the output data stream. If you get errors after the FEC correction, your pickup's have problem on their own or discs are heavily scratched.
@@DrCassette Actually the service manual says the CDP-710 is using BurrBrown PCM56P that is a well respected DAC on its own. The similarly looking CDP-750 is indeed using the Philips TDA-1541.
@@enricoself2256 The service manual must be wrong then, or they made different versions of the CDP-710 for different markets, because I have clearly seen the TDA1541 on the board of the CDP-710 with my own eyes ;)
Surprised you find so many CD players with headphone jacks.
My parents had a Technics CD player that looked very similar to that one. Maybe even the exact same one. Good memories. I'm still a little mad they sold all that their HiFi components without telling me.
I think the pioneer would a good one to start on. I;m a fan of Pioneer equipment. Thanks
Love your videos :) would love to see you repair the Sony CDP-710 ... They are actually a super machine in disguise :) definitely worth repairing. Keep up the good work, many thanks from a fan in London 😄
The Sony CDP-710 has actually already been repaired, it went so fast, I did it off camera. Cleaned the laser, cleaned the loading mechanism belt, resoldered the RCA output connectors. I am indeed impressed with the Sony, the built quality is good (bottom panel made from 2 mm thick steel), and the TDA1541 DAC gives very good sound quality, very pleasant, not as harsh as Sony CD players usually sound.
Das Pioneer und das Onkyo Deck sind ja schonmal garnicht so schlecht, auch der Philips CDP. Das Pioneer kann gut so ein Gerät sein, das sein Leben lang in einer Schule, etc. verbracht hat und den ganzen Tag lief. Oder eine Spannung am Display fehlt. Hoffentlich bekommst du alles wieder zum Laufen :D
Der Technics CDP sieht auch toll aus.
Au ja und das Akai mit dem GX-Kopf.
Reparier' das Pioneer als erstes.
Das Pioneer muss in der Tat für Jahre einfach durchgelaufen sein. Ich habe den Farbfilter von der Front entfernt, sodass das Display nun offen liegt. Nun kann man es lesen, aber nur, wenn es im Halbdunkel liegt. Es ist also wirklich das Display, die Ansteuerung ist in Ordnung. Auch im Gerät kann man die Betriebsstunden sehen, über den Spannungsreglern ist die Gehäuseabdeckung innen schwarz.
@@DrCassette Ja das ist schon ordentlich. Sind Tonköpfe und Andruckrollen auch so verschlissen?
Wir haben zwar kaum eigene AM-Stationen, dafür kann man aber schauen, wie gut der Empfang der AM-Stationen im Umland von Deutschland sich gestaltet. Ein paar gibt es noch - insbesondere im Osten. Manchmal erstaunlich, wie gut ein Tuner die dann noch empfangen kann. Lokal haben wir auch noch ein Sender auf Mittelwelle.
MfG
I have a question for you - I have a TASCAM cassette deck model 102 - great deck but I was playing a Jackson 5 cassette in it, while it was playing ,the pitch dropped about half an octave, but stayed steady but slow. What could have caused that, and is there a way to fix it? Thanks!!!!
Some nice gems there.
That Sony CD it's "wow" trust me on this. I have one. You have to press on the mechanism. I have same problem with CD door. You have gold there
The Sony CDP-710 has already been repaired. Indeed it is a very nice CD player. The TDA1541 DAC gives very good sound quality, very pleasant, not as harsh as Sony CD players usually sound.
Love these vids! 💖
Gotta be the pioneer cassette deck followed by the akai g6
good youtube channel
Thank you :)
Have you made any progress on the Telefunken so far? I highly suspect worn belts and either very dirty switches or leaking capacitors......
I have not started working on the Telefunken yet. The belts are certainly bad, as for the oscillation, it could be a dirty record/play switch, but since the Telefunken has a full logic mechanism, I don't think it still has such a switch. Finding the cause of the oscillation might turn into quite a challenge...
Andrea Berg, I wonder who is gonna miss the CD lately 😄
Love your videos my friend hope your doing well
Ohh, noch mehr neue Sachen! Meine lieblings Komponenten sind galube ich das Pioneer und Telefunken Kassettendeck. Deswegen würde ich von diesen auch als erstes die Reparatur sehen! Das Pioneer würde ich gerne sehen weil ich Pioneer Sachen aus der Zeit relativ gut finde, und das Telefunken weil ich vor ungefähr einem Jahr den passenden Reciever dazu gesehen habe, und ich das Design sehr gut finde.
Der Philips CD spieler ist das lower end Modell von dem CD618, über den du vor kurzem ein Video gemacht hast.
Viel Glück bei den kommenden Reparaturen!
Beim Telefunken stehen die Chancen glaube ich ziemlich gut, wenn ich das Oszillieren beheben kann, ist der Rest wohl nur die üblichen Riemen und Reibräder. Beim Pioneer bin ich leider nicht so optimistisch, offen gesagt finde ich Pioneer aus der Zeit schrecklich, sowohl in Qualität als auch Servicefreundlichkeit waren andere Hersteller da besser. Wenn das Vakuumfluoreszenzdisplay selbst kaputt ist, dann war es das. Aber vielleicht ist es nur etwas in der Ansteuerung. Allerdings sind mir nach den Videoaufnahmen in der Beschichtung vom Gehäusedeckel Unebenheiten aufgefallen, kann sein, dass es da auch ein Problem mit Rost gibt. Das Pioneer ist in ziemlich miesem Zustand, das war im Video nicht gut zu erkennen.
Ich persönlich finde Pioneer aus der Zeit eigentlich sehr gut, ich hatte noch nie Probleme damit (nicht so wie Sony Sachen aus der Zeit, welche mit Problemen geplagt sind), und die Qualität ist zwar nichts ausragendes, ist aber von dem was ich von anderen Herstellern aus der Zeit gesehen habe nichts schlechtes, und die Performance von Pioneer ist auch sehr gut. Jedoch ist das alles meine Meinung, und ich habe auch wenig Ahnung.
Wenn der VFD jedoch kaputt ist, dann macht es wenig Sinn sich mit dem Mechanismus zu beschäftigen.
@@lampenundco Was meinst du? Wie kann man was beheben?
Very interesting, I hope you will fix these!
Would love to see how neat is the internal design of Telefunken as I'm fond of German Engineering.
The Telefunken would have already mostly been made in Japan. Not much German engineering in there...
@@DrCassette recently I obtained a blaupunkt stg 2091 and was amazed how it's fully functional since 1971.
Maybe the clicking noise is from the common brittle gear problem for the Technics RS-TR230. I think that's a common issue for those units. Hope you can repair the GX-6, that's a nice unit.
The Technics RS-T230 turns out to have all kinds of intermittent problems. All functions of the recording deck are affected, sometimes there is no fast forward, or no rewind, or the take up reel does not turn in playback/record. But when you keep trying, eventually these functions will work perfectly, until they randomly break again. The gears all seem fine, I have not seen any made from the brittle soft plastic. The best explanation I have so far is that it seems like a plastic part over the years has bent because it was under tension from one of the belts. And because of this bent plastic part various other parts of the mechanism don't align with each other anymore.
Update: After taking apart the deck I have found the brittle soft plastic gears. Except in this deck they had not lost any teeth. Instead they had turned even softer than usual, so a lot of times instead of engaging properly, they would just bend out of the way, causing the intermittent operation I described. Since two replacement gears cost more than what the deck is worth, it has now been scrapped. Sorry.
I ran into that issue too with the replacement gears being too costly compared to how much the deck is worth, but the gears in my deck had chipped teeth. Glad you found the issue, though.
That first JVC cd player sounds great, and what a surprise that it still works! I am curious about the repair of that Pioneer cassette deck. I have a similar Pioneer deck that does not turn on, no response at all. I wonder if you can get the pioneer and the Akai working again! Good luck!
Thank you :)
Please repair the ONKYO cassette deck first. It seems to be the most interesting.
I agree, another vote for the Onkyo.
The Akay Deck
great vid,,,,,subscribed,,,,
Thank you :)
I have the slightly bigger brother of the phillips CD600 , the CD610 , its a fantastic sounding player and has the twin DAC system not found on the CD600. its been used almost daily since 1989! the slight delay is normal.
twin dac is clearly advertised on faceplate of cd600 seen in this video
@@piwex69 According to forum on-line twin dac is mostly marketing; the player contains just one DAC TDA1543 which the datasheet says it is a Dual 16 bits DAC, so every player with a TDA1543 has a TwinDAC. The input is indeed a single serial bus where L and R bytes are interleaved but the DAC internally has two independent DAC's working at 4x oversampling.
Yes, great machines. I have the CD634 from the same range, it has some pretty awesome features.
@@enricoself2256 Then both cd600 AND cd610 are exactly alike, single TDA1543/SAA7220 advertised as dual dac.
I like the AKAI mostly. Could you fix the problems?
The Akai cassette deck will get repaired, but as I said in the video, it will be a very complex repair, so I might not be able to make a video about the repair process.
It is a pity, it would be interesting to know how you fix it, although it is complex. I can send you a 🌻 to persuade you 😊 Maybe you can show some dissemble ans assemble processes a bit faster?
I screw the pinchroller of, clean and lube the shaft, that sticky grease is a pain, i have plenty Sony DAT players in service a wile back same story, Black glue grease 😂 😂
I know in the end all I need to do is take off the pinch roller assemblies and clean out the sticky grease, but I have a feeling there may be a lot of disassembly involved before I can even get to the pinch roller assemblies...
man thats funny the Telefunken tape deck when u pushed play not good lol ! loud bad noises never good maybe you can fix it nice looking machine ....
