Hi there, I managed to replace some resistors to get my 317 working some weeks ago with the help of the forum.
Now, for some days, my left speaker is noisy, distorted. Especially when basses are played, it's horrible.
It's from any input: pc from a midi device, TU-217 tuner on tuner input, and what I use to test: a vinyl-player on the phono in with a Daft Punk Alive album (cause there's enough of bass to test).
What I did: opened it and put contact cleaner on the switches, from the inside, turned them slowly and on moderate speed to help the cleaning. This helped to get rid of the crackles on the balance (especially around the dead-point on +-0 ). Overall it helped a bit, but compared to the right speaker, the left is unacceptable.
What can I measure inside the amp? (i have the plans from the internet and have "basic" eletronics skills, a multimeter and some spare resistors.)
