yea exactly. Not trying to be an alarmist or anything, but we cherish these older things, and if you say, blow a transformer, or a now discontinued SMPS switching IC on a portable logic board, How are we going to fix it? we arnt. Its going to be up to the engineers (like myself) to find a work-around to the damage in the power supply.

Anyway, When i disassembled this unit, i happened to notice it, like uh-oh... here we go... Its hard to say the conditions the Duo was in before I got it. its basically scrap now, but it does have a good logic board and stuff. Going to pull and save the inverter for another person that has a bad one.

So i cannot say if your caps are bad or good, but seeing what I saw, change them anyway.

Also, the 35V caps appear to be the 24v DC input filter. the other 2 appear to be the DC-DC filters.
