Thanks.  I'll try these things out.  The shop has a pretty good rep --
one of the techs worked for Roland in the early 80's in Japan in their
repair department [his initials were on the inside of my 100M] -- it's
the only one around here that I know of (in NYC!).  Anyone know of any
very good synth repair places in NYC area (I have no car, so must be
nearby)?
