(this in response to my suggestion about a method of grounding oneself
to keep from frying a MOSFET)

AIEE!  Good (excellent!) point!  I hereby retract my suggestion for a
simple wired body-ground... especially as any equipment that has a CRT
tube probably has some VERY dangerous voltages in it.  I forgot the
rule-of-thumb that says "when working around voltage, stand clear of
all possible grounds and keep one hand in your rear pants pocket".

Thanks, Chris, for pointing this out!  Once again I seemed to have
proven the adage that a little knowledge is a dangerous thing.
