I have never bothered going beyond re-capping output capacitors when repairing power supplies. Most of the time, I fix hardware because I hate throwing stuff away that should have worked for much longer. But now that I have an oscilloscope, I can poke around places I would not have bothered with before. This repair is one I had been meaning to take another stab at for nearly a year. Why bother with a decade-old power supply? Because I can! Should you use a decade-old power supply? Probably not.
I skimmed it over, quite interesting read, normally I stay away from Tom's but thought this was worth linking
I put in a comment recommending he do a follow-up with a DM311 mod
