    Hey All!
    Im currently trying to repair a Marshall s80 given to me by a friend. He brought it to me stating that it quit at a show. No face LEDs will light, only the power light. No sound either. I know its a power stage problem, and after replacing the two 4700 microfarad caps right after the transformer, im seeing that current is once again flowing but the issue still persists. ive seen nothing else on this problem, and im at a loss. Any suggestions on what to check next? what other spots could it be? ive had my meter to it all day.

    thanks again,
    -Matt
