RE: Old amps, was Re: Far out man!

Alan raises a good point about the possibility of a "hot chassis"... and
if he's right, you should not use that turntable in a circuit with any
other audio equipment.  It's a hazard to EVERYTHING.  You can possibly
isolate it using a low-current isolation transformer, but ultimately it is
a very dangerous piece of equipment.  Even in high-voltage tube amps (a
tube guitar amp can have upwards of 500v!), the most dangerous part by far
is the AC mains.  Power transformers limit the heart-stopping current.
