PURPOSE:To correct the lowering in the power supply due to the rise in the load impedance, by supplying the power for the band deficient in the power from the tap at a primary side or another winding provided at the output transformer. CONSTITUTION:The signal input to the input terminal I of an amplifier A1 is made for the voltage amplification and impedance conversion with the amplifier A1. The amplifier A1 is connected to a primary windings N, N' of an output transformer T3 via the 1st input transformer T1, and is connected to amplifiers A2, A2' in push-pull operation and also to the 2nd input transformer T2 via the parallel resonant circuit of a capacitor C0 and inductance L0, and the 2nd input transformer T2 is connected to amplifiers A3, A3' in push-pull operation, connected to the taps N1, N1' respectively provided to the primary windings N, N' of the output transformer T3. |
