Hello all, my name is Will.
I'm not sure of the rules around these forums. I'm not even sure if I'm posting this in the correct spot. I hope that the moderators would move my topic if it's listed incorrectly. I've got some problems with one of my vintage receivers.
I'm inclined to learn about this older technology, but my understanding is very limited. I have had very basic experiences soldering or understanding the units and components of vintage technology. I've had plenty of experience building and repairing newer modules and hardware, but this is a different discipline. The only way I see to repair my vintage receiver is to ask for help from the veterans.
So! I'll get to it.
Initially the problem first occurred when I tried turning the receiver on. It was years ago and I had a poor understanding of the power and heat running through this unit. Give a kid something cool and of course they'll break it.
Anyway, I had left the receiver running too much. I was playing video games for extended periods of time with this unit running, so it got ran down pretty quickly. I didn't have any fans to displace heat. When I attempted turning the unit on, I remember hearing an abrasive noise. I don't remember exactly how it sounded although I know it wasn't good.
I turned it off. I turned it back on, then I started to smell burning. It was strong, I shut it off immediately.
Over the months I had a couple of people look at it. They basically looked around the inside of the unit, turned it on, smelled burning, then shut it off real fast.
I held onto the receiver for a few years and then I decided to take it to a repair man. The email communications I had with the gentleman give a very basic idea of what was being attempted.
"sorry I forgot
TAD7129p
if you find them we need 2 of them.
one works but static sound
the other no sound on the channel at all
thanks I will keep looking as well."
So, that's the best description I have of one of the possible directions to head toward in this repair. The gentleman was looking for the part TAD7129p. I've been told that certain characters can be the manufacturer's numbering, so maybe not all digits are required for locating this part.
It's also evident that these parts aren't necessarily obtainable on their own. I'll probably have to purchase another SA-600 to get one of the receivers working. Apparently the gentleman that worked on my receiver also did some other things to the unit.
- Located a car fuse inside the stereo, replaced it with the proper fuse. (This was the reason the unit burnt up in the first place, the fuse did not fail properly)
- replaced the light bulbs and cleaned the controls.
- Restored unit so it no longer burns when turning on, although the channels don't seem to work anymore.
He was saying that he had managed to get sound to come through one or possibly both of the channels, but it had poor quality. He removed whatever parts he had installed to enable the poor sound, so now nothing comes through at all.
I'll run through a basic summary of what happens with my receiver when I turn it on.
- It turns on, light bulbs and back light turn on.
- Audio source has no effect. Sound does not come out of the receiver at all, not even static.
- Smells good. Smells like stereo. Cleaned recently.
That's all I've got. If anyone would like to help me solve my problems, I'd be forever grateful. I'm sorry if the post is full of useless details, sometimes I elaborate too much.
I will be in the process of obtaining a service manual for an SA-600.
I'll upload the service manual to this thread, if that's possible.
Thanks for reading!
Will.
