And another thing, as long as I'm at it, how come when we did this that
everything up to the tube blew up?  I could understand the relay smoking,
but why did everything AFTER the relay go?  That means that the amplifier
(tube) was drawing the current to cause everything to explode.  That doesn't
jive with the shorted relay problem.
