A local vintage/record shop was having a garage sell on as-is items and I picked up a Pioneer SA-6500 ii for $20. I brought it home to try it out and it powered on fine. The issue is in the left channel; when I turn it up the sound is fine at 2 on the dial, but when I increase the volume there is bad distortion in both the a/b left channels. The right a/b's sound really good and all other switches work. I didn't have any deoxit, but I sprayed the Radioshack brand cleaner in all the pots and worked them around, but had no luck. I am thinking the record store probably already tried cleaning the pots or they wouldn't of sold all their units as-is because its an easy fix if it works. I know a lot of people are looking for these units and wouldn't mind spending money and time to fix them or need them for parts. I would like to get this unit working myself if it isn't too much work for a newbie, but I want to get an idea if its worth it or I should just sell it as-is online. Does anyone have an idea of what the problem could be? Or does it just need a recap? The board is very small and simple, so it would be a good first recap project, but I would need the exact part list. Thanks.
