If you think you're having power supply issues, the very first thing you should do as a matter of practice on equipment this old is to replace all of the electrolytic capacitors in the supply. Caps have gotten smaller, so I usually replace them with at least twice the voltage rating. IMHO, 35V caps are too small for a 30V supply...
While you're at it, it wouldn't hurt to replace the rest of the electrolytic caps, but I'd stick to the stock values if they are in the audio path.
