Repairs to Spectral preamp

My Spectral DMC 20 phase reverse switch is noisy.

Spectral bo longer services due to age but says its likel a noisy relay?

. I need a reliable repair

Shop. I'm in Vancouver, BC, Canada. Thanks.


A relay makes sense, ask if you can get the schematics/part number and whether or not it is a plug-in.  Lots of relays are in sockets so it's a 10 second job after you get the cover off.

Agree with jond - and very disappointed with Berkely. Won't buy 

Anything else of theirs. Eric, any chance you know a competent service

Shop. I'm not concerned about shipping costs, and have original boxes.
