摘要: This invention provides a way for the user of an amplifier to select the class of operation of the output power tubes. A microprocessor monitors the bias conditions and makes the necessary adjustments to set the amplifier in the user selected class of operation. In one embodiment of this invention the user selects the class of operation via a switch. The microprocessor calculates where the plate current should be per the selected class and adjusts the grid voltage until the proper plate current is achieved.
