The EIMAC 3CW40,000A7 is a ceramic/metal
power triode designed for use as a high power
RF amplifier for industrial and scientific applica-
tions. The high-Mu grid in this tube provides
excellent isolation and permits stable operation
as a grounded grid linear amplifier in class AB or
B. With simple cathode bias the tube operates in
class C for high efficiency. Its water-cooled anode
has a maximum dissipation rating of 40 kilowatts.
