ABSTRACT:
A voltage multiplier device is disclosed which includes a circuit and a means for coupling the circuit between a television filament transformer and the heater filament leads of a C.R.T. picture tube of a television set. The device is operative to develop a voltage across the two leads of the C.R.T. heater filament that is greater than the voltage developed across the two secondary leads of the transformer.
