Recently my friend asked me if i could fix his svt classic. when you plug into the front you get nothing. so i checked the power amp by plugging into the return of the effects loop and it works perfectly. the standby light stays red and according to the user manual it is not getting high voltage to the tubes. if anybody has any ideas they would be much appreciated. thanks in advance guys.
i already have it torn apart on my work bench i just need some help narrowing down where the problem could be.
