Abstract

741,465. Valve generating circuits. COLLINS RADIO CO. Dec. 2, 1953, No. 33506/53. Class 40 (6). An oscillator comprises a tuned circuit C1, L1, coupled to a valve V1 whose gain is reduced to the order of unity or less by means of a cathode feedback resistor R1. The anode circuit of the valve V1 is coupled to a valve V2, the screen grid of which is provided with a load resistor R5 and is back-coupled via condenser C3 to a tap on the tuned circuit. The output is taken from the anode circuit of the valve V2. The arrangement is more particularly intended to give improved stability and reduce the influence of output loading upon oscillator frequency.
