Best! Probably need to shut it down, replace all capacitors (electrolytic and 'paper' types,) as they are certainly faulty or nealy so. Want to do a revamp, I would also replace carbon resistors which have long ago drifted way out of tolerence or thermally challenged. Then there is corrosion which of course contributes much to erratic behavior, and my favorite is Deoxit, but I don't work there or anywhere else anymore.

Sub a pair of ten cent diodes for the rectifier if you need to rectify the problem further.
