It must be due to the march of progress that all the replies so far
discussing Vdd and Vcc, etc., have not mentioned Vbb or V++.  Does anyone
have a good mnemonic for remembering these? Or how to label the screen
voltage or grid voltage?  All this "solid state" stuff is just a ridiculous
fad if you ask me.

How about Vpp for plate voltage, Cgk for grid-to-cathode capacitance,
triode, so g is assumed to be g1.

As I recall we used g1,g2 and g3 ... gn (like a pentagrid converter where g
could be g1...g5). So the screen voltage would be VGG2 wouldn't it?

       As voltage is often represented with the capital 'E' letter, that
screen voltage could be EGG2 too  ;-))
