I powered it up on a variac and the power bulb comes on and it has a tiny line in the display. Most likely the tube is toast, but I can't find a manual anywhere.
Finished up the bathtub reverb, but the LED is not coming on and am getting no sound. I have gone through it several times but I thought a pair of fresh eyes might find something I did not.
A buddy of mine just fried his Supro 1650R amp. From initial viewing it looks like two resistors are toast.
The board is so toasted that I can't tell which resistors are bad.
Does anyone know if there is a PCB layout of this board?
