Hey folks,
I'm working on a Crate CR-165B amp for a friend. I've had many issues, but i want to take one at a time. I'll include the schematic for reference.
this issue is with the poweramp/supply. Resistor R21 is burning on powerup. I do not have the preamp/control board connected, and I do not have the board heatsink screwed to chassis. I have replaced about all the transistors on the board except Q3 which checked ok. Diodes have been checked/replaced. C15, and C16 replaced. Any ideas ?
