Help Needed: Pioneer VX 350 from the 70's: Crackling on the right side on and off

[Steven Ray]

It started crackling on the right side on and off. Well recently I took it almost completely apart and cleaned all the boards and everything I could.
When I put it back together it sounded like new But then the right side started crackling again.
Iz there anything I can do to stop it¿
I mean it sounded a little worse than when you don't have a station tuned in...

Try DeOxit (or a good contact cleaner) on the volume control as well as all other controls and switches. IMHO with vintage gear dirty or corroded contacts are the greatest source of trouble (even more so than bad capacitors or noisy transistors). It sounds like you are on the right track.

If you had a scope you could trace a signal through the unit to see where the noise starts. I know that It can be very frustrating when you think that you have the problem fixed and then the noise starts up again!

Bumping up the thread here. It sounds like it’s still not working?

I don’t know how much about fixing equipment. But if you can find a schematic (sometimes you could find one online or on eBay ) and know how to solder and find parts (if needed), vintage equipment can be fixed in many cases, depending on what condition they’re in. Others can tell you much better than myself.

Short of this, you would need to try to find somebody who knows how to work on vintage equipment near your area. Hope this helps.
