How I soldered new CAPACITORS to fix my GM Delco Radio

My 35+ year old Delco car stereo had lost sound in the right channel. I found these very helpful sites that explain the re-capping process. I had never done anything like this before, and I had some major struggles along the way. This was not a typical easy DIY job for me, as I have no experience working on printed circuit boards.
All the credit goes to these 2 sites:

Where I bought Parts:

About to do this same project on the same exact radio. Thanks for doing the leg work and posting the parts list. It helps a ton!

Good luck. On mine, I still had the same issues after installing in the car. I think the Amp chip was bad, even though it probably needed caps replaced anyway.

I love simple and cheap fixes like this. I can’t tell you how many electronic parts I’ve picked up over the years, and all any of them needed were a simple repair. In this day and age, everything is disposable to 99% of people. Just toss it and buy a new one I guess. Pretty sad.

@nowherefastgarage Жыл бұрын

These old radios are getting harder to find, and a lot of them need repairs. There are places that do it, but it's expensive to have it done or buy one already refurbished. This was a good learning experience for me.

@@nowherefastgarage Nothing wrong with trying something you’ve never done before, especially when you end up with good results. I have boxes of these old Delco radios from the late 70s-late 80s. Most of it is pretty rare, but unfortunately not too desirable. At any rate, good work 👍

it is almost always the Capacitors....If the unit won't power up it will be the Capacitors in the power supply...this applies to Televisions as well.

Ok man, i want a follow up on this radio fix - to see the radio working or not - up above the basement. Hey man, I dont know if you've seen this guy on youtube: "Bits Of Wisdom", he's got one of these camaros (alot like yours) and he's a retired gm engineer doing awesome informational videos on the third gen z28. You guys might help each other's channels out with likes and coments and referals for us 3rd gen types!

@nowherefastgarage Жыл бұрын

Okay thanks, I will definitely check out that guy's channel. I did not do any further testing on the radio. But I have the same static on a known good radio when I hook it up this way. I will eventually get back to it.

COOL MAN!! lookup Third Gen Guy - he had a video on how to solder new capacitors to fix the speedometer!

Great info. I am curious though, had you thought of buying one of the inexpensive 4 channel class D amplifier boards from Amazon and perhaps a Bluetooth board which would allow you to have better functionality and have a much more powerful output? If so, I would love to see how to wire this in. I have an old radio like this and would like to keep the stock look but have better power output to the speakers.

@nowherefastgarage 10 ай бұрын

That sounds like a great idea, but I'm a complete novice at stuff like this. I finally got this radio into a car to test, and it still has the same original problem of the right channel going out. So I assume the amp IC is actually bad, not the caps.

I have a 91 Lesabre that has the same symptoms . L&R channels and F&R don’t work right . Only clear sound is on front left speaker .

After I installed it in the car, still having cutting out issues. I think the amp IC is bad on that channel.

No, after I installed in the car, it still had the same original problem. They say it's either the caps or the amp chips. I guess mine was the amp chip. There are people that offer this service. That would be my recommendation. I'll get you a name if you need it.

The three compasitors are the easiest thing to fix but time consuming I fixed mine for 89 cents for three but 2 hours start to finish😊

Yes, I agree. It's a lot of labor time.

the same radio in my 89 s10 had no audio at all, and i think i found the problem....c19 has completely leaked, and the board is covered in corrosion. i could even see it through the gap in the complete radio. oh well.

I would like to know how to fix the "tuning" dial. My radio isn't picking up radio stations well, and keeps sqeaking as I try to tune it in.

I'm sorry but I don't know much more than what I did here. I have had the same issue with my radio in my Grand National not picking up stations as good as it used to. Seems to be a thing with the Delco radios from that era.

I found someone had posted them on the internet for the 80's radios, I'm not sure if the 90's are the same. You could also look at them on the board, they should show a value printed on them.
