More unhappy capacitors



My power supply started emitting smoke today. Opened it up and found some bulging capacitors and greasy residue on the top of the chassis directly underneath them. Two 4700uF @ 16v caps. I don’t have any of those values on hand, so I had to use a pile of different ones to do the repair. Fortunately the PCB is resting on a set of metal standoffs so there was adequate room to solder some in underneath.


I put everything back together and it works fine now. I had to adjust two pots for the variable +- 15vdc outputs. The +5v and -5v were spot on. The AC 6v out measures 7v and the AC 12v out measures 13.5v. Nothing I can do about that, those lines come directly out of the transformer.
