Evancox

I own an oscilloscope, multimeter and variac. I have replaced all the electrolytic capacitors on the amp boards and power supply, I have replaced the diac, triac and Optocoupler, also replaced the -12v zener diode. The issue I’m having is getting the triac to fire like in the service manual. My amp has the first version of the power supply.

Hello everybody, my name is Evan and I’m new here. I own an old Carver M400 in the champagne color that I’ve been trying to get working again. Hopefully I’ll be able to fix it with some help from you guys.
