Just did it again tonight after a few weeks off. Hate to take it to a hack as the unit has sentimental value and I don't want it damaged. Hard to ship as it probably weighs 50 lbs.
Any thoughts or ideas? I'm not afraid to pull the cover off and spray some contact cleaner around but thought I'd defer to the brain trust first.
Thanks.

You cant hurt anything with contact cleaner.....(famous last words).
Great amp, its good to see there are still luddites that haven't succumbed to the nonsense of 5:1. Two ears, two channels....
Inspired by this thread, I finally dragged my 80's Accuphase out of the cabinet, removed the covers and bathed it in contact cleaner. Its a monster amp, but with some annoying switches that cause problems similar to the ones you describe. Lo and behold, its fixed.....
Contact cleaner rocks. Ive got a Yamaha guitar amp, since the 70s. Its never failed, despite daily use. Last month, it started to misbehave. Oh well, I thought, it hardly owes me anything.....dismantled, contact cleaner sprayed liberally around the pots....next day- as good as new.
Long live Contact Cleaner.
LeeH, those mono block valve things look awesome.
