CPI 3CX1500A7

The 3CX1500A7/8877 power triode is designed
for use as a cathode driven Class AB2 or Class B
amplifier, in audio or RF applications including the
VHF band or as a cathode driven plate modulator
Class C RF amplifier. As a linear amplifier, high
power gain may be obtained without sacrifice of
low intermodulation distortion and high amplification factor combine to make drive requirements
exceptionally low for a tube of this power capacity.
