300B is directly-heated type cathode triode, used as class A1.

1. GV 300B Plus uses Nanometer carbide nickel-plated iron as the anode, and at the same time, the anode surface area is increased in the design, so that it has a greater anode plate consumption than the ordinary 300B.

2. It has excellent linearity and is able to produce a more realistic and clear sound, making it ideal for audio amplifiers.

3. It adopts a unique high voltage, long time aging method, in the production stage will be unstable, not withstand pressure products removed, to ensure that the factory products can continue to work steadily.
