3CPX800A7

The Penta Laboratories 3CPX800A7 is a ceramic and metal power triode intended for use as a radio frequency amplifier in FM broadcast applications. Operation with zero grid bias offers circuit simplicity by eliminating the bias supply. In addition, grounded-grid operation is attractive since a power gain as high as twenty times can be obtained with the 3CPX800A7. The slightly longer ceramic improves the maximum plate voltage capability while maintaining the same tuning characteristics as the 3CX800A7.
