Hello everyone, I am trying to repair this power supply. I have already replaced the two large smelly bulk capacitors. Also there was corrosion on the heatsinked diodes and the solder side of the board and ran . When I first powered up the scope when I got it worked like normal for about 5-10 minutes then suddenly shut off and never worked after that. I tried this supply back in the scope after I replaced the parts and still nothing.
I did hear a really faint clicking sound from coming from the board almost like a relay. I also hooked this up to a variac out of the chassis for isolation and powered it up and hear the same clicking sound. I measured across about 165v dc at both the bulk caps.
Here are some some pics
