So i went and found some 51Ω resistors and some IRF840A's from the surplus store, threw them into the power supply, tested it, and it appears to be fully working as now when its set to full power it outputs 31V instead of 500mV. I also found some 470uf 50v KZEs that i plan to put on the output, but i think they're NOS so i may have to reform them first (they still test within spec).

Once i'm done with testing, i'll post photos of the repair
