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. Beam Power Pentodes Rule, Dewdz! Tom 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? Jack --- Outgoing mail is certified Virus Free.
