I had a wanptek 60v 5a bench power supply. It blew up one day. I diagnosed the problem to be blown MOSFETs and diodes on the high side. the bridge rectifier was shorted also. A thermistor was also blown

I changed the MOSFETs and diodes. the rectifier then read as expected. i replaced the thermistor with a shorting wire.

Upon turning on, it blew again. So, I have no idea what's wrong with that. I've bought a replacement as I don't have time to mess about right now.

Here's the replacement! It seems good.
