B barber02 Member Joined 2018 2019-11-16 5:20 pm #1 2019-11-16 5:20 pm #1 I am wondering if anyone could tell me what this diode is in the power supply. It connects to pin 11 of the PWM board (D206). I found it shorted. I’m going to take one from a parts amp that I have but I need to order some to have in stock.
