	At WSC, there were a number of explosions of Televideo terminals (the
old 912c's, to be exact), traceable to capacitors on the monitor boards.  This
was corrected (it was thought) by replacing the capacitor that was on the board
(a _polar_ capacitor) with a non-polor capactior, as it was documented in the
original specs.

	This seemed to clear up the problem... until some time later when
>*BOOM!*<; another terminal goes to terminal heaven.  When the building got
conditioned power, we thought that was the end of it.  >*BOOM!*<, another one
went, within a week of the power conditioning.

Moral:  Don't use the same power line for your Televideo terminals as you
do to send the 50v synchronization pulse from your centralized clock system!
