Vintage Simmons Drums (UK) Users Group

Hi all,

I'm sure this might have been asked before but....I just aquired an
SDSV and everything seems fine as far as power and triggering, but
there is no sound output from any of the outputs. Has anyone else had
this problem? If so, what was the fix, if at all. I'm sure I can find
a repair shop that can make sense of the schematics, but it would be
nice to not be going in with no reasonable idea of what the issue
might be. Thanks in advance for any ideas or hints.

Tom
