...power-amplification ratio. The plate efficiency is relatively low (20 to 35 percent). (2) In Class B, the grid bias is approximately equal to the cut-off value so that the plate current is approximately zero when no exciting grid voltage is applied, and so that the plate current in a specific... | |
