ABSTRACT:
A cathode ray tube (CRT)/deflection coil assembly is provided which includes a signature resistor for indicating the deflection sensitivity of the deflection coil. An amplifier circuit with an adjustable gain supplies current to the deflection coil. A gain adjustment circuit measures the value of the signature resistor and provides a signal to the amplifier which varies the gain of the amplifier to compensate for variations in the deflection sensitivity of different deflection coils.
