The smd resistor has a 2R00 marking, it has a resistance of 2 Ohm.

And she is alive again! Woohoo!

Turned out I had to replace R51, which had changed its resistance. It's a small SMD resistor, so this might not be for everyone.

Kudos to the Moog suppport team, got a really nice mail with some ideas and that nailed it!

Yeah, thanks!

I actually wrote an email directly to the Moog support guys a week before opening this thread, but haven't heard a word yet. Not even a "we don't help DIYers" or something.

Totally different from what I am used to from Doepfer here in Germany.

I'll update this thread with any ...

I've measured some of the parts following the power input traces. Looks like the board is two sided with a ground pane inbetween.
I've checked the diodes, resistors and capacitors in that area and I'm suspecting one of the following two diodes and coils:

D2, Marking ...

Good question :) Asking myself, duh...

The two pin power connector with the cable sticking out towards the backplate seemed to be too tight, so it made more sense to me to connect the cable facing inward at that time, it was dark and the plastic guides are easily bent. I successfully connected and ...

Hi fellow moogers!

I'd be greatful for any advice on what to replace or check on my Mother-32 mainboard. I did not identify any fuses or protection diodes near the 2pin power header.

I've had a little mishap with my Mother-32. I was using it in my eurorack perfectly fine and decided to rehouse it ...
