Well, my C2 saga continues...
About a month ago, I dug into the C2 and pulled the Balance pot as I was having issues. I did add the 2 resistors, but used 220K instead of 185K as that was the closest I could find at Radio Shack.
It worked better, but I was still getting some volume drops and irregularities, especially when wiggling the volume pot shaft. I messed about with the ribbon cable from the Balance board to the Volume board and found when I held it in the center and wiggled either side that the Volume side gave issues, but not the Balance side. so I reflowed the connections in hopes of curing it, but it still arose.
FF to yesterday. I found my mini screw drivers and went into the Volume pot to clean it. I managed to remove the rear cover far enough to get some Deoxit on the rear wiper and plate, and reassembled it after working it about. It worked, but after some variances it settled down to a smoother, but lowered output.
Today I fired it up and it sounded fine, nice and clean, for about 45 seconds and then it dropped down about 10 dB or so all of a sudden.
Any ideas? The drop after turning on makes me wonder if there's something more to this than simple mechanical issues, like bad caps or transistors?
Any and all help is appreciated!!
