With all the "epoxy" talk it sounded hard to fix, but this actually looks pretty easy. Seeing this I envision an even easier fix: remove the PCB completely and put this piece inside: IRM-10-5 Meanwell PCB all-in-one switching PSU.
Hello, with some PSUs it is easier, with others it is not. Mine here was very easy to open, but I have also had some that were very difficult to open. Sometimes too much epoxy has been filled in, which makes reworking even more difficult. The idea with the IRM-10-5 Meanwell is a good one. However, this model has a ripple of 200 mVpp, which is very high. Computer chips from the early 80s are sensitive and should not be exposed to high ripple for too long. In another video, however, I followed a similar idea and installed a voltage regulator that had a ripple of about 20mVpp.

One more question: how did you open it?
