I visited my soon to be 93 year old father over the week end and had to get his "system" up and running for him.....again. He has an old Fisher receiver from the 70's that hardly works, an old something or other turntable and a dried out 10 inch speaker system. So the turntable wasn't sending anything to the amp and it was buzzing and popping or doing nothing at all. So first I had to check out the wires coming out of the arm for continuity, then the RCA cables that were patched together in four different places with wire nuts and electric tape. Next I had to remove the input jacks and re-solder a wire onto one jack. The turntable selector switch needed cleaned but I'd have to disassemble the whole cabinet as the top is not removable and he didn't want to do that. Still didn't work so I pulled the needle cartridge out, removed all the wires and cleaned the posts, connectors, and needle. Then it worked if you ran it in mono but not stereo, so I hoped he wouldn't notice. He didn't. For a little while, then it quit again, so I took the cartridge out and jammed a little piece of notepaper stock under the contacts to raise them up for better contact. Then it started working in stereo, but not mono. So I said, "Good enough, don't touch anything." He was happy, we put on a Mitch Miller album, the Ink Spots, and Doris Day. Not much bass but it works and he's happy. I keep forgetting to look at Good Will for a new system for him.
