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!

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, AlexIMG_5581.jpeg
 
I've been very lucky with PSUs and machines in general, I've only had one bad Q610/PM6100 style PSU and it was dead when I got it. I have a project to fit a Meanwell RPT-160B in the housing since it outputs sufficient amps and fits with room to spare for the original fuse and switch. I'm using the original PCB as a mount. But since I have multiple working PSUs it's not a high priority!
