Need help to fix Optinica 1414 amp
Hey all you audio heads! New member here. I was able to get a vintage Optonica amp and tuner at a garage sale a few years ago for less than $10.... but the amp has always had a "dead channel" (left or right will not go until it warms up) It seems that if I roll the dials a bit it gets going, but then fades in and out until it warms up, listening right now after being on for 2 hours or so. Sounds good ....
About a year ago I opened the chassis and sprayed all of the pots with contact cleaner. No help.
Any suggestions greatly appreciated. Looking to replace it and keep the nice tuner, still a great deal.
