Very nice and complete. Thanks. By the way; getting finger prints (oil) on any kind of incandescent light bulbs will reduce their Life span by 50% minimum. If it happens you can clean them with a dry cloth before turning them on . :) Happy trails everyone.
Excellent video. Appreciate you posting your tutorial on changing the lamps on this pioneer stereo. We all at one time or another will need to replace lamps. Now we know how to do it!
Great video! This tuning dial light seems to be one of the most difficult places to access within this whole receiver. I never would have had the confidence to try this without this video tutorial. That part is so fiddly! Again, excellent video. Like art.
Great Video! I wish I would have saw it earlier. I had to replace all lamps on a SX 1010 including the meter lamps and dial scale lamps AND the dial pointer lamp. It is a very delicate operation, but I was able to do it and did not brak the pointer. Just be careful bending back the small metal tabs that hold the bulb in the pointer.
Hi. Just wanted to thank you for this video. Gave me confidence to order replacement lamps and fix my sx-424. Appreciate the detail and the quiet step by step. You are skilled.
Hello Marty, thank you for your kind words! Yes, the receivers from the 70s are great stuff, I love my 434. Many people don't realize just how well made these 40 year old machines are and I agree with you completely, they are often underrated. I bought this receiver as non-working, it was cheap for about 400 Czech crowns in 2010 (about 16 USD). The situation with classic audio gear pricewise is a little different here in the Czech Republic (also in Slovakia), things cost more. Somebody "had a lot of fun" with this receiver before it found its way to me, it was in a very sad shape. Nothing worked, everything was blown. The fuses, lamps and all the main transistors. And also one knob was missing. I replaced the lamps and had the electronics fixed for 2000 crowns (78 USD). Total cost for the receiver, all the lamps, one missing knob and the repair was about 3600 crowns (about 140 USD) with all the shippings and handlings. And it was definitely totally absolutely worth it. The sound is fantastic and there is no way I would be getting such build quality for 140 dollars nowadays. All who visit me are impressed by the receiver, even though it's an entry-level model. Thanks again for watching! All the best, Matthew
Very good video! I just bought a STA-77 this week. The owner had replaced the dial lamps but missed the indicator “needle” lamp. After watching I feel pretty good about changing it out, it takes two bulbs. Thanks!
@@mikelane3611 It went well. These are a bit of a chore but to see the old receiver all lit up is rewarding. Since my post, I’ve noticed that the meter lamp has failed so I’ll go back in. I had bought this from a fellow who thought he’d replaced all of the bulbs but the lamps for the tuning needle were out. I searched all over for yellow and red bulbs this small but didn’t find any. I ended up using red and yellow paint used to tint stained glass to make one of each. The glass paint dries clear so plenty of light. I found that this receiver has to have that stereo red light bulb working as it’s part of the circuit! Good luck with yours.
Ah, the SX- 434 receiver. I bought my first hifi system with overtime pay in Nov. 1975. Got the Pioneer SX- 434 at The Wiz audio store in downtown Brooklyn for $127. Also got a BIC 920 turntable with Shure M70 cartridge and KLH 31 speakers for $120 at Uncle Steves on Canal St. NYC. Time went by and I traded up in components. A few years ago at work they were throwing out an SX- 434. I took it to my fix-it guy and for $60 he restored it. Now it sits in my kitchen and powers a Nakamichi BX- 1 cassette deck and Boston Acoustics A- 40 speakers. I would NEVER sell my SX- 434. Such a low powered receiver (15 wpc), with a good FM tuner and phono section, a tape monitor loop and an aux input, plus a mic input, WOW, so much for so little. Not just Pioneer, Onkyo, Technics, Kenwood, Nikko, Sony, they all made quality stuff. Don't believe me? Pick up any 500 watt surround receiver. You only need one hand. Then try to lift a vintage 15 watt receiver, you'll feel the difference. The new receivers are all PLASTIC, no wood or metal. These 15 wpc units were not for big sound in large rooms or to drive large inefficient speakers. But for the den or bedroom (with your best girl) or any room, say 10ft x 10ft, like my kitchen, they are great. Especially with efficient speakers like my A- 40's (5 watts minimum power). Besides what other products will last 40 years. Please don't ever underrate these marvelous budget receivers.
It should be noted that the soldering technique you're using is completely wrong in case any beginners are watching. Always heat the wire/metal parts being soldered until hot enough to melt solder then apply the solder to the joint...do not apply solder to the iron unless you are tinning the tip.
Do you have to discharge the capacitors before starting a job like this lamp replacement? I’m a novice so I’d like to first take the proper safety precautions (since I know just enough to get myself into trouble).
@@russt2237 It is best to have everything discharged, yes. The larger the capacitor, the bigger the shock. Better safe than sorry. However, replacing the lamps does not bring you close to any capacitors. They are on the PCBs. The front of the receiver just contains the dial, buttons and knobs.
I agree. There is nothing more irritating than watching an instructional video with a narrator who constantly interrupts by explaining what the hell he is doing.
The red "stereo" indicator comes on only to indicate that the receiver is receiving and successfully decoding a stereo signal. The "mono" pushbutton does not affect it. Let's say you are tuned into a station and the red "stereo" indicator is on. If you push the "mono" button, the red "stereo" indicator stays lit, even though you are getting a mono sound out of your stereo speakers. The FM section in the receiver is sending a stereo signal to the amplifier section, but there it is combined into a mono signal (when the "mono" pushbutton is depressed).
I got mine from dgwojo-com, but if you know the dimensions and values, you can surely get them in any well-stocked electronics shop. Lamp specifications for the SX-434 are in the video description box above.
I think that you can't go wrong with either, if they are up to spec, both Pioneer and Marantz receivers from this era are great. Marantz is more expensive, but I don't think Pioneer is "worse" soundwise. They were all expensive quality electronics and are still highly valued because of their sound, build quality and aesthetics. My advice is this: get the one you like. Have it checked and serviced if necessary, it is absolutely worth it. It will be a pleasure to listen to, look at, and use for many years to come.
I967 thx, i do agree Marantz is more expensive, but if you say sound wise it does the job I will see, I have a Yamaha Cr 420 and was looking for another decent amp, I run the amp on some Boston Acoustic A100 and Pioneer Pl-A25, usually at low volume, would like more presence ...thx for the tips and quick answer...and great advice...cheers 🍻
Thanks man! With your video, I changed that pointer lamp on my Pioneer SX-535, love that amp! But now a new problem is the right channel crackling only when using phono (can't use my turntable). I tried to DeoxIT everything inside I could see... nothing changed :( Any idea?
So I just cleaned the 5 fuses... and now on Phono, right channel sound fades out as I power the receiver... but works fine when I push the "mono" button. Please help me!!
Crackling phono - check the connectors for loose connections, perhaps something needs resoldering. It could also be a faulty cable - try replacing that first, see if the crackling persists. As for the fading channel, the same thing - I would first check for loose/broken connections. If everything is solid and connected and the channel still fades, the capacitors need to be checked and replaced where necessary. It's difficult for me to say where could the problem be without seeing the receiver in person, but I would start with what I have said above. Good luck.
Hi there - all the lighting has been gone for a while behind my 434, though there was a time I remember when the frequency display was partially illuminated. I changed the 5 fuse bulbs and dial pointer lamp yesterday but when I turn the receiver on, none of the lights work... Could you shed some light on this issue? Thanks
Hello Mackenzie, Very likely (99%) this is just a blown fuse. Turn the receiver upside down, remove the bottom metal cover and check the fuses - one will be blown. On my receiver it is the one farthest from the power transformer, I have the 220V model. Just be sure to unplug the receiver from the mains before you do any work and get the exact replacements for your fuses (amps and volts rating). Hope this helps. Matthew
Thanks for your reply! Replaced all the fuses with the right amps/voltages. All voltages were 125V, and there are 2x4A,1x3A and 1x1A. When I plugged it back in and turned it on, no lights at all coming from the front, and checked the fuses again and the 3A had blown... I don't know if it helps but the "Fuse Line Voltage Selector" on the back is set to 220v, 1.5A. Thanks for your help
Mackenzie Sykes Well now we know that something keeps blowing the fuse, maybe a short - I really can't help you with that from here. The line voltage selector should be set to the voltage you have at home (240 for EU, 110 for US), I don't see a problem there, if you say the receiver works and plays music. Check the connections and wires near the lamps and going from the lamps, maybe there's a short somewhere.
sorry to bug you but would you be able to provide a link to where I would be able to find the dial pointer lamp and the strereo indicator lamp as I cant really find anywhere to buy them online. Thanks for your time to make this video.
WOW! After watching this great video I know what NOT to attempt on my own. Can you tell me what you or another shop would charge to replace the lights? Thanks.
I have no idea what would a shop charge. If you brought me a receiver and a full lamp set, I'd do it for 20 euros / dollars. But I am not a shop, I do this in my free time. I guess the shop would be more expensive.
1967, a question. I have my SX-434 driving four speakers, a pair of Synergistics S-12B 8ohms, min power 6w and a pair of Boston Acoustics A-40 8ohms, min power 5w. Am I correct that combined they present a 4ohm load to the amp?? Do they also present a total min power of 11w?? Is this a safe load for the SX-434 receiver?? Just curious..
Marty Jewell The manual says: When two pairs (A+B) of speakers are to be used at the same time, each speaker must have an impedance of 8 ohms or more. Your setup is fine. The receiver will handle it alright.
Awesome video so helpful. I have the same receiver with the same pointer light needing replaced. Can you please tell me where to get the replacement light for the dial needle?? Thanks
1967, hate to bug you but I'm now having a problem with one lamp on my SX-434. Sometimes it lights and stays on, sometimes it doesn't. Will that be a bulb issue or is it a short?? Don't effect the sound but aesthetically, it pisses me off. Would hate to have to drag it in for repair.
Welcome back, no problem! I think that it's most likely that the lamp is going. The filament is getting weak and it will eventually burn out completely. If that's the case, just follow what I do in the video and replace it yourself. Dial / scale lamps are the easiest to replace, you just unscrew the metal thing in which they sit (4:32 in the video) and it's a quite simple and straightforward pop-out pop-in operation. Hope this helps.
Hey!! thanks for the video!! it's really helpful for me... i'm going to follow the steps... DO you know where i can find it?? it's a normal pilot lamp 8v ?? Thanks in advance!!!
Greetings! Thank you for your kind words, I am glad the video was helpful. The 6 dial lamps are 8V 0.3A (30mm x 6mm), the dial pointer lamp is 8V 50mA (5mm x 3mm) and the stereo indicator lamp is rated 6V 30mA (approx.9mm x 4mm). You can also get the lamps here: sites.google.com/site/dgwojocom/
Hey!!! just one more question... I have just got my unit which i bought in internet and it's not working like it should be.... i mean it works but it make and horrible noise in one channel.... do you have an idea what it could it be?? maybe one of the fuse at the back??? Is it repairable?? thanks a lot!!!
I was just wondering if you ever had to replace any of the five lamps behind the tuner display? I'm asking because last week I took possession of my dad's X-434 and I'm in the process of getting it ready to be used in our master bedroom. I already cleaned the silver faceplate with aluminum wheel cleaner(worked wonders!) and I'm about to replace all of the five lamps since eventually all of them blew in the course of it's long life. The rest of the bulbs are still working so I'm gonna leave them alone except for the AM/FM signal strength bulb which uses the same bulb as the other five. I figured I'd change it while I'm in there. Anyway, I know I can go with the more readily-available 250mA lamp although I've also found the 300mA lamps online which are what Pioneer used at the factory. I'm just wondering if it really makes a noticeable difference in brightness?
ForeignerPhan All of the lamps in my receiver were dead when I bought it, I had to replace everything. The dial lamps I have are 300mA 8V, they are bright enough, in my opinion. You can order both types and see which one you like better. The difference in brightness - I can't really say, I would have to see for myself. All I can say is that 300mA ones look wonderful, the dial is magical on these vintage receivers. Good luck with your repair.
Thanks for the feedback. Only the far left side of the dial was illuminated when I turned it on for the first time in ages two weekends ago and when I turned it on again later in the day that lamp had burned out as well. It didn't really matter as I was planning to replace all five of them anyway but at least I have a reference point to go by. I was only 14 or 15 when my Dad brought home the 434 in the mid-70's so it has some sentimental value to me as well. The unit hasn't been used much in the last twenty years so it's pretty much pristine inside and out for the most part. Like you, I've always loved the styling of these vintage Pioneer receivers so I'm kind of excited to get it back to it's former glory. Thanks again for the bulb info.
After much thought I think I'm gonna go with these cool blue LED's: www.ebay.com/itm/LAMP-KITs-SX-424-SX-434-8v-COOL-BLUE-LEDs-VINTAGE-STEREO-RECEIVER-DIAL-METER/322936290808?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2055119.m1438.l2649
Yeah, the cool blue LED's worked out great. In fact, I also replaced the tuner "stereo" indicator bulb along with the bulb which illuminates the tuner needle. I noticed right away the bulb housing on my 434's tuner needle was somewhat different than your set-up. I also discovered the part of the needle which sits in the housing was VERY brittle from heat and age over it's long life. I eventually had to put a dab of GOOP adhesive in the bulb housing to hold it in place. The plastic rectangle housing on the "stereo" indicator bulb was also kinda brittle and missing part of one side so I just framed the entire thing with a small piece of duct tape so there wasn't any light bleeding through. Hey, it worked ;) When I turned the unit on afterwards I made sure to turn off the lights in the room beforehand to see the old girl in all her glory. She's purdy again...just like I remember her from my youth.

Thanks for watching, I will be making a new video on this receiver, the lamps have burned out again.
Almost forgot to mention, great repair video! Not boring at all and I did watch it end to end. Gonna save it, never know when I'll need it. Thanks.
Hello Marty, thank you for your kind words!
Yes, the receivers from the 70s are great stuff, I love my 434. Many people don't realize just how well made these 40 year old machines are and I agree with you completely, they are often underrated.
I bought this receiver as non-working, it was cheap for about 400 Czech crowns in 2010 (about 16 USD). The situation with classic audio gear pricewise is a little different here in the Czech Republic (also in Slovakia), things cost more. Somebody "had a lot of fun" with this receiver before it found its way to me, it was in a very sad shape. Nothing worked, everything was blown. The fuses, lamps and all the main transistors. And also one knob was missing. I replaced the lamps and had the electronics fixed for 2000 crowns (78 USD). Total cost for the receiver, all the lamps, one missing knob and the repair was about 3600 crowns (about 140 USD) with all the shippings and handlings.
And it was definitely totally absolutely worth it. The sound is fantastic and there is no way I would be getting such build quality for 140 dollars nowadays. All who visit me are impressed by the receiver, even though it's an entry-level model.
Thanks again for watching!
All the best,

Greetings! Thank you for your kind words, I am glad the video was helpful. The 6 dial lamps are 8V 0.3A (30mm x 6mm), the dial pointer lamp is 8V 50mA (5mm x 3mm) and the stereo indicator lamp is rated 6V 30mA (approx.9mm x 4mm). You can also get the lamps here: sites.google.com/site/dgwojocom/
Thnak you very much for your help!!!!
You're welcome!

Is it repairable?? thanks a lot!!!
I was just wondering if you ever had to replace any of the five lamps behind the tuner display? I'm asking because last week I took possession of my dad's X-434 and I'm in the process of getting it ready to be used in our master bedroom. I already cleaned the silver faceplate with aluminum wheel cleaner(worked wonders!) and I'm about to replace all of the five lamps since eventually all of them blew in the course of it's long life. The rest of the bulbs are still working so I'm gonna leave them alone except for the AM/FM signal strength bulb which uses the same bulb as the other five. I figured I'd change it while I'm in there. Anyway, I know I can go with the more readily-available 250mA lamp although I've also found the 300mA lamps online which are what Pioneer used at the factory. I'm just wondering if it really makes a noticeable difference in brightness?
ForeignerPhan All of the lamps in my receiver were dead when I bought it, I had to replace everything. The dial lamps I have are 300mA 8V, they are bright enough, in my opinion. You can order both types and see which one you like better. The difference in brightness - I can't really say, I would have to see for myself. All I can say is that 300mA ones look wonderful, the dial is magical on these vintage receivers. Good luck with your repair.
Thanks for the feedback. Only the far left side of the dial was illuminated when I turned it on for the first time in ages two weekends ago and when I turned it on again later in the day that lamp had burned out as well. It didn't really matter as I was planning to replace all five of them anyway but at least I have a reference point to go by. I was only 14 or 15 when my Dad brought home the 434 in the mid-70's so it has some sentimental value to me as well. The unit hasn't been used much in the last twenty years so it's pretty much pristine inside and out for the most part. Like you, I've always loved the styling of these vintage Pioneer receivers so I'm kind of excited to get it back to it's former glory. Thanks again for the bulb info.
After much thought I think I'm gonna go with these cool blue LED's: www.ebay.com/itm/LAMP-KITs-SX-424-SX-434-8v-COOL-BLUE-LEDs-VINTAGE-STEREO-RECEIVER-DIAL-METER/322936290808?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2055119.m1438.l2649
How did it go? Did the blue LEDs work out?
Yeah, the cool blue LED's worked out great. In fact, I also replaced the tuner "stereo" indicator bulb along with the bulb which illuminates the tuner needle. I noticed right away the bulb housing on my 434's tuner needle was somewhat different than your set-up. I also discovered the part of the needle which sits in the housing was VERY brittle from heat and age over it's long life. I eventually had to put a dab of GOOP adhesive in the bulb housing to hold it in place. The plastic rectangle housing on the "stereo" indicator bulb was also kinda brittle and missing part of one side so I just framed the entire thing with a small piece of duct tape so there wasn't any light bleeding through. Hey, it worked ;) When I turned the unit on afterwards I made sure to turn off the lights in the room beforehand to see the old girl in all her glory. She's purdy again...just like I remember her from my youth.
Lindo!
