[Elecraft] Positioning of the KPA500

[Merv Schweigert]

Seems there could be a problem with the grids in the tubes sagging and 
touching the
plate if not operated in the proper position,  I do know that the 866A 
rectifiers will
not work, the mercury will puddle on the sides and cause arcs,  they 
need to be
operated vertical.   :-)

Good ole days eh?
