Interconnect quandry WTH!

Must be the relays. I'll have to figure out how to get at them. There is only one is that correct. I've looked around the unit a bit and seen one. It's the plastic clear box. Pretty sure the board must be removed to remove the relay if I'm looking at it correctly. This will be my first electronics surgery! We'll see how it goes.
Thanks.

When you wiggle the cable, does it also cause varying degrees of hum? If so, I would first change the RCAs. It would probably be an improvement regardless.
 
This amp has sat probably 42 years of its life unused. It's truly a mint example of this model. I am the first to remove any screws in it. Kinda cool. It has had a wood cover on its entire life.
 
I cleaned all switches and knobs and jacks three times. I know the phrase blow out the dust is tounge in cheek, but it's unreal how spotless this thing is inside.

So any thoughts on it being transistors at this point?

Also how do I find a replacement relay. Would it be in the manual. I'm thinking Omron maybe.

Relays are relatively generic. You shouldn't have trouble finding an equivalent.
 
Ok thanks. I found a drop in replacement.

So is it somewhat safe to rule out noisy transistors at this point? I don't know what they sound like when they go south.
 
You can't rule it out til you solve the problem. I don't think a bad transistor would cut in and out. More like severe over drive. Think volume too high in a 9v transistor radio.
