ABSTRACT:
A field effect transistor is used to short circuit the timing capacitor of a gaseous tube when power is interrupted or removed. The short circuiting of the timing capacitor prevents the residual capacitor charge from being added to a new charge after an interruption so that the early firing of the gaseous tube is avoided and damage is prevented.
Because capacitor charging always starts at zero voltage when the field effect transistor is used, hysteresis, at low voltage outputs, from the gaseous tubes is greatly improved.
