Hello
I have a Roland  US-2 and sold it on Reverb. The buyer returned in saying it didn't work. I have no way to test it. where can I send it to get repaired? Thanks in advance!

The US-2 are pretty simple.  Most of the lines are just connected from the input to both outputs.  The switching just mutes one or the other synth units by cutting the synth volume signal to that unit, pin 9 I think.  Schematics are available from Wayne Joness' site: https://www.joness.com/gr300/service/US-2-Service-Notes.pdf.   Probably something simple like one of the Opamps died.  Any competant electronics tech could figure out the problem.

hey pickle6, i'd be interested in getting that from you, if you still have it. or i can repair it, as well, not a real big deal usually.
