Let's see, a 1AG4 draws 1.25V at 40mA for the heater. That's 50mW. An ordinary dekatron, at 450V and 500µA is 225mW. Are there any submini pentodes with G3 pinned out separately? Yup, the CK511X is one. More interestingly, the 8522 is listed as a "dual control" pentode, like a 6AS6, although it draws the usual 6.3V @ 150mA for the heater, same as a 6AS6/5725. The folks on the bay claim a Russian 6J2P is equivalent, I wonder. - John -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
