The 3CW20,000H7 is a high-mu power triode
intended for use as a dc voltage or current regu-
lator, or in a high voltage switch tube or pulsed
regulator service. In addition, since the tube
is identical to the 3CW20,000A7 except for the
anode and grid flanges and the addition of the fila-
ment flying leads, it is useful as a zero bias Class
B amplifier in audio or RF applications.
