Stereo Problem

Anyone know about electronics? I'm trying to fix a 44 year old stereo. :(

I got mine for college in 1978, not the same type as yours.
After reading your post on the other forum, its safe to say you probably know more than anyone here.
I did some soldering a few times but I don't design.

Hmm.

I assume you're replaced the fuses already and cleaned all of the fuse contacts with rubbing alcohol. Hissing and buzzing sounds can come from a variety of things. Moisture trapped in the solder contacts is a popular culprit. Old wiring can cause this sometimes too - corrosion in places you can't see can cause arcing of current. Likewise, a cold solder joint or a joint that feels secure but isn't quite right. Sometimes the joint will feel and act solid until you run current through the system for a while. The heat from the current can cause minute cracks in the solder joints over time which could cause the buzzing. Could be bad diodes or worn-out parts damaged by heat from soldering. :mystery:

Problem is, trying to find these issues? Pain in the arse. If you're careful with a multi-meter, it is possible to use an Ohm-meter setting to find said cracks in the joints, but tricky. Cold-solder joints that cause buzzing will sometimes make the needle dance as the current goes through the joint.
