The Power Amplifier is designed to driven by the T41-2 Low Power Amplifier, described here:

The Low Power Amplifier combined with the Power Amplifier are intended to replace the original V11 Power Amplifier which uses IRF510 switching MOSFETs in the final amplifier stage. This new design will improve all aspects of power amplifier performance, including linearity, power, efficiency, and bandwidth. An important difference is that the amplifier…
