Hi David,
Thanks so much for your reply.
I have tried plugging into all the outputs and get absolutely no sound. Do you think it's likely that the capacitors on the power supply are shot? That should be relatively easy to swap out. I just got done building one of those x0xb0x 303 clones so my soldering iron is begging for more work ;)
My 100 has a blue panel. Another interesting bit about it is that there was a modification done to it. It has 5 additional 1/4" jacks and an additional knob. They are all positioned together to the left of the EML 100 logo on the panel. I am guessing it was not a factory mod since the jacks don't really line up perfectly. They are labeled:
Knob - "input rate"
1/4 jack #1 - "Sampler Input"
1/4 jack #2 - "Sampler Trigger Rate-Ext Output"
1/4 jack #3 - "Trigger Output"
1/4 jack #4 - "Sampler Output"
1/4 jack #5 - No label on this jack
I uploaded a couple of pics to the group page so you can get a better idea of what it looks like:

Regarding the schematics. Are the 101 and 100 similar enough that the 101 schematics would be useful in repairing the 100?
Thanks kindly, Sasha

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.
