3-500ZG Transmitting Tubes

The RF Parts 3-500ZG™ is a compact power triode intended to be used as a zero-bias Class AB2 amplifier in audio or radio-frequency applications. Operation with zero grid bias simplifiers assocated circuitry by eliminating the bias supply. In addition, grounded-grid operation is attractive since power gain as high as twenty can be obtained with the 3-500ZG™ in a cathode-driven circuit.
