Default Re: QW-MS3010D 30V 10A Variable PSU Blown MOSFET

How do i test the drive circuitry? as it appears the drive circuitry is driven off its own separate power supply.

The main driver IC is a KA7500B (U4), the other two chips are LM324N (low power OP-AMP) (U6) and DK112 (low power SMPS driver)(U1).
