  • Abstract
    With class-A operation, loaded-plate-circuit Q does not affect plate efficiency. With extreme class-C operation, Q has a considerable effect. A Q of 50 is required to keep loss in efficiency below 3 per cent. To obtain full benefit from the tank capacitor it must be connected directly from plate to cathode. Connecting the plate or cathode to a tap on the plate inductance results in lowered efficiency.
