Default Audiopipe power supply driver card

I had an Audiopipe 2000 watt amp come into the shop that had a very heavily damaged power supply driver card. I just so happen to have an Audiopipe 1500 watt in the shop waiting for parts with an intact driver card. The difference being the the driver circuit was on the main board verse a daughter card like the 2000 watt amp had. The driver circuits were the same so I was able to reference the 1500 to repair the 2000.

Having said all of that, I thought I would post some pictures of the circuit for future reference for anyone else that may need it. I used KST812 PNP for the M6 transistor and KST1623 NPN for the L6 transistor and MMBT5551 NPN for the G1 transistor.

Here is a picture of the caps in the driver circuit for the power supply.
