I'd like to second a request for info on Serge grounding issues. Could
someone knowledgeable give the non-EE types among us some basic tips?
Like, what, exactly, is a "ground loop"? I have some problems with my
recently-acquired used Serge as well. Sometimes (it's hard to
characterize when) things like oscillator frequency are very sensitve
to disconnected systems - even, e.g., the location of my hand! This is
very disconcerting. It's not just a matter of letting the system "warm
up", either. The other main problem I have is that my SEQ8 often
outputs a non-steady voltage (when not clocked!).

I've just gotten an oscilloscope, so I can start nailing down just what
it is I'm seeing. But it's tricky when the behaviors are not 100%
reproducible.

Thanks,
