Abstract
In a television receiver, an automatic kinescope beam current limiter circuit includes a current path between a beam current sense point and an interating capacitor across which a control voltage is developed. A threshold conduction device causes the current path to exhibit different impedance characteristics and associated response times so that the limiter circuit has the ability to respond to average beam current values, as well as to above average r.m.s. beam current values such as may be associated with peak beam current conditions.
