Anyone here tech on Memorymoogs?

Before I ask complicated repair questions, does anyone here repair or work on the Memorymoog that could offer some power supply troubleshooting tips (original supply)? I have some questions and trying to get some clarification on what I think is wrong.

I picked up a very nice early MM the other day very cheap. I think I have 5v rail issue.

Disregard- I got it working. Shunt resistor solder joint was cracked.

Now on to the fun parts…

Broke it again… slipped with my DVM checking voltages at the DMUX board and shorted something… was 5 minutes into a calibration when I did that …
