Re: 7704A (et. al.) Inverter Regulator Question
I just checked those with my component checker (without U3105 plugged in as I wasn't sure what effect that might have) and, yes, I have several bad tantalums so those will be replaced. Oddly, C3150 is bad (measures about 32pF). I really didn't expect that one and, to be honest, thought the smaller tantalums would have been okay. I was wrong.toggle quoted messageShow quoted text
I wish I'd realized all this when I had the board out. Some of those can be replaced without having to remove the board but some, particularly C3150, may not be possible.
This poor power supply has had a rough time of it...
