I just fired up my new Modulator, driving a 10K resistor instead of
the PA. It works well except the efficiency is low. The HV is about
2500V. Idle current is about 60mA (150W). Efficiency at 400W RMS
output is 42% as calculated by plate voltage times cathode current.
Does this seem typical for this configuration?
