ABSTRACT:
A pair of current sources, each having a high output impedance, are coupled to a pair of first and second inputs of a differential input stage of a vertical deflection amplifier. An output of the amplifier is coupled to a vertical deflection winding. A current sampling resistor is coupled to the first input via a first resistor. The second input is coupled via a second resistor to a terminal of the sampling resistor that is remote from the first resistor. The first and second resistors are matched resistors for providing differential driving.
