Curious, I heard reports of similar voltage regulator issues from an O300 or O350 owner as well. Maybe these are just getting to that age!
With regards to mine, I have replacement parts for that whole block, from the LT switching controller, to the switching MOSFETs, to the capacitors. I suspect more than just a bad capacitor given how one of the MOSFETs seems to be stuck and overheating, so I am hoping that just replacing it all will do the trick.
I ordered the parts some time ago, but with everything going on I have not had the chance to pull the board and put it under the knife (so to speak). It is a big board that I am sure will be annoying to pull, so I am not very keen on it, but it is definitely on the to-do list since I am reluctant to use the machine until the issue is resolved.
