The output port of this circuit is connected with the output jack of the wobbling frequency signal generator, the wobbling frequency signal is rectified and adds to the Mosfet T1. The PNP transistor T2 adjusts the operating point through the potentiometer RP, the output signal is led to the final stage transistor through the transistor T3. The output signal of the final stage transistor's collector adjusts the low frequency oscillator's anode voltage with correct polarity.
