So you're the guy who wrote "BEWARE - Breaker on back of panel" on that
piece of plywood. Heh, heh. <G> I got curious the first time I turned
the switch off and the LV PS lights stayed on down on the bottom of the
front panel of the Tx, so I started looking around. Yep. There it was, 
hidden under the the bottom unit of the PowerSide on the back of a panel 
sporting another breaker switch on the front side.

Who woulda thunk anybody would do something like that? But then, there 
is or was a guy around this market who has been known to do some totally 
inexplicable things (at least by all known standards of engineering 
practice). Probably one of those in most markets.

Therefore .....

My motto is "Don't trust nuthin' until you've tested it yourself WITH
test gear you have tested yourself. Then keep one hand in your pocket
and work in rubber soled shoes."
