Hi Aron

 

Your -15V regulator device is short circuit.

Hi everybody,

First post here. I have a MicroMoog that's been sitting around for a long
time.
I opened it up and the first thing I noticed is that the -15V rail is around
-22V and no adjustment of R106 affects the negative voltage. It IS putting
out a steady 15+V.

Any ideas on where to start?

Thanks,

Aron
