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.
