Abstract
An over voltage protection circuit for preventing excessive high voltages which exceed the X-ray isodose limits for human beings when the high voltage primary winding, the tuning coil, or the high voltage primary driving winding opens. The B+ voltage for the driving oscillator or horizontal driver is derived at a point in the circuit such that when circuit elements fail, the B+ voltage is removed thus turning off the drive to the high voltage circuit.
