Class 38 (4) [Also in Group XL (c)] In an automatic D.C. voltage stabilizer of the series valve type deviations of the E.H.T. output voltage are detected by including a constant current device in the output potentiometer and measuring the voltage drop across this device. The device consists of a pentode V6 connected as a cathode follower, a second pentode V7 forming the cathode load. The screen grid voltages for the two valves are obtained from an auxiliary source A, A, that for V7 being stabilized by a neon tube N4 and that for V6 being stabilized by N5 which is connected with the cathode of V6 via a further cathode follower V8. The output potentiometer thus consists of resistor R1, valves V6, V7 and resistor R2. The voltage across the valves V6, V7, i.e. between points a, b, is compared with a reference neon N3 and controls the amplifier pentode V3 controlling the series valve VI. Point b is connected to the amplifier via a cathode follower V5. The amplifier V3 has a pentode V2 with degenerative feedback as its anode load so as to present a high impedance. The screen voltage of V3 is stabilized by a neon tube N1 and that of V2 by a neon tube N2 coupled via a further cathode follower V4.
