right channel is cutting in and out so i blasted all switches and knobs with deoxit, symptoms still continued. discovered today by freak accident if i wiggle the amp and a few of the diodes surrounding it the both channels work perfectly and sound awesome. do all these components need to be re-soldered onto the board or any other ways to fix this problem?

Probably a dry joint on one of those components, though worse case is that there could be a hairline crack on the board around there too but I doubt it. Just retouch the solder joints around that location to reform a good joint and test.
