Troubleshooting Crown Amplifier Power Supply.

Troubleshooting Crown Amplifier Power Supply.

I have an XTi 4002 that won’t power up. The IGBTs where blown as well as one of the trackers. I replaced the IGBTs & closely associated resistors, transistors, as well as the gate driver as this was instructed in the service manual. I also replaced the CH.1 tracker parts that were fried.
