stage, a 6V6-G tube will give an output of 4.25 watts maximum with an input signal of 12.5 volts peak on the grid. A smaller input signal gives a smaller output; 12.5 volts is the maximum the tube will handle without producing Other output tubes will have different ratings. Theory of Operation: Refer to the schematic diagram below.

Class A Power Amplifier Design Basic considerations for low (audio) frequency operation. 1. Power usually delivered to a low impedance load. 2. Signal usually has little, preferably no dc content. 3. May have low frequency content, as low as 20 Hz. Emitter follower circuit has best power transfer efficiency, since its output impedance is low.

bipolar (bjt) transistor families for audio power output stages. …. there are many technologies by manufacture to reach perfect data so as high linearity and transit frequency. The newest is "BiT-LA" (ST) and older versions are "M.E.T" (TOS), "LAPT" (Sanken), RET (FUJ) and EBT (NEC). I think, there are many more versions without especially abbrevation.
