is that hum/buzz coming from the power supply.. if so you could have a diode that is going south.
as long as the resistors and the caps arn't burned out they psu should still be able to give sufficient power to boot.
but when it comes to sustaining current and diodes are brought into the mix with the caps this COULD in theory cause the issues you've seen.
Disclaimer: this is based on experience with other forms of electronics, e.i. analog valve guitar amps, think marshall plexi
if the power section of the amp wasn't working right... nothing worked right.
Do you have a DMM( digital multi meter) and test points on your board?
