Power Mac 6100 PSU Dyna Comp. DCF 803

Hi Mac enthusiasts,

I recently acquired a Power Macintosh 6100, unfortunately the power supply is not working. After inspecting it further, I found out, that parts are actually missing, U1 and R1. I cannot find any high res pictures online to get the name of U1 and the resistivity value of R1.
If by any chance someone can provide a picture of the PSU section would be highly appreciated!

Thanks in advance!
Cheers, Alex

those aren't "missing", they're not populated on that board.
look, you can see a jumper placed on the lower 2 holes of the DIP footprint.

Hi finkmac, thanks a lot for your feedback! Are you sure this is the case here? The previous owner did soldering at that position, at least it looks like that. Appreciate your opinion! Regards, Alex
