I am considering replacing the caps in my PSU, as it is decades old. In doing my homework before starting the project, I came across these photos of the PCB. Some of the caps have connections that I do not know. I expected just two pins for each cap, but...
- C1 and C2 have four, maybe six, solder points. My guess is that two holes are bodged for a pin spacing that was not that drilled originally. And, that the remaining two might be for a jumper wire, between two pours... But, this would mean the jumper is under the cap?
- C3 and C4 have two, maybe three, solder points. My guess is that one hole was bodged for a pin spacing that was not that drilled originally.
- C9 looks as I would have expected, two pins.
All of these caps have a "SSS" silk-screened between two of the pins. I could use some help with what this symbol means and its orientation, too.
This is the Bottom PCB Photo. Top of PCB photo and Schematic are on the following posts.
