If this is a new problem, I would 'guess' at a capacitor or several are damaged from age.
Replacing all the 'big' caps in it would do the job of making it as good as new.
(under $100, and if you can do it yourself solder decently, under $35.)
Nearly ALL problems with older amplifier stuff starts with bad capacitors.
