re: 813 supply voltage
-
One of the more infamous West Coast types used a
4 hole, then expanded out to 6 a tube 813 amplifier
with nearly 4KV on the plate.
-
This famous "Wescars Check-in Amplifier" is where
I learned that the mfgrs max supply voltage was not
a max value written in stone... and could easily
be "pushed up."
-
813's were so cheap back in the 80's he just kept
a couple of sets of spares around if required.
-
Using the amplifier SSB only, he never had a
problem and the amplifier still has the original
tubes on board (now retired as he's not as active
on 40 these days).
