Abstract
A television receiver having a horizontal output transistor includes a collector and an emitter respectively connected to a first potential and a second ground potential, a first series circuit of first and second damper diodes connected between the first potential and ground potential, a second series circuit of a deflection coil and an S-shaping capacitor connected in parallel with the collector-emitter path of the transistor, a retrace capacitor connected between the first potential and second ground potential, respectively, a third capacitor connected between the cathode of the second damper diode and the second ground potential, a first voltage supply source connected to the first potential through a choke coil, and a second voltage supply source connected to the anode of the second damper diode through a primary winding of a transformer of a load circuit, the voltage E.sub.1 supplied by the first voltage supply source being selected greater than or equal to the voltage E.sub.2 supplied by the second voltage supply source.
