3CX 1500A7/8877

      The 3CX 1500A7/8877 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.
