A no-sound-at-all problem may be something simple.
Have you tried plugging directly into the VCO outputs?
If none of them are working, the problem is almost certainly
in the power supply. If they do work, work your way through
the filter mixer, the filter, and then the VCA to see where
the sound is getting stopped.

Can't help you with the repair shop, not living in that area.
However, I can tell you this much: the 100 is a lot more rare
than the 101. I'm not sure what kind of demand there is
for the 100, but I see 101's going on eBay for $1500-1700.
Out of curiosity, does your 100 have a blue panel or the
grayish-white panel that the 101's have?

The 100 is pretty easy to get into. If it's like the 101, there are 5
screws around the perimeter of the panel that hold it in. Remove
those, and the entire panel comes out with all of the circuitry;
nothing is mounted to the inside of the case. The circuit boards
are pretty clean and easy to work on. The biggest problem you
may have is that I'm not aware if there are schematics for the
100 still around anywhere.
