I built up an SSE a few years ago, listen to it daily and really love it. About a week ago it started getting a really weak quiet right channel. Swapped the power tubes and put in different tubes, no change. Opened it up and look for loose connections, or anything showing obvious damage, but could not find anything. Does anyone have any recommendations for starting to trouble shoot with the multi-meter? Any suggestions appreciated, thank you!
If you just record all the voltages to ground on all the pins, and post them here, that should highlight an electrical issue. Other wise it could be a connection - RCA input, speaker, so a poke with a plastic stick sometimes pays dividends.
