Eml synthesizers

Hello,

I was lucky enough to be handed a free EML 100 the other day. It
powers up, but I get no sound.

Can someone recommend a good repair shop in the Bay Area for these
synths? Also, curious as to what the value of these are.

I have a decent understanding of circuits - are these simple enough to
troubleshoot on my own or should I leave it to the experts (assuming
they are still around!).

thanks kindly.
