I picked up this 2220B in a package deal, and the guy told me it was dead. After reading lots of threads here, about resurrecting dead units, I assumed it could be fixed. Here are some pictures of what I have.
Faceplate looks very nice.
Inside top, not so much.
Then I pulled the bottom cover.
So I assume with all that dirt in there, every pot is full, preventing signal to pass. What should I do? Is there a way to clean all that dirt off without damaging the components? It's stuck pretty good, I rubbed on one of the circuit boards to see how stuck it was, and it came off, but not like dust. Air blast isn't going to do much of anything.
My goal is to get it going with minimal cash outlay. Where do I start?
