Между трансформатором и конденсатором 2 включен электронный стабилизатор тока ЗП, питающийс  ;1мпульсами наир жени  пр моугольной формы от ограничительного усилител  ОУЯ. В качестве прибора дл  измерени  напр жени  на зажимах конденсатора 2 служит ламповый вольтметр ЛВ. Лампа 5 {6Ж4), на которой построан ограничительный усилитель, вместе с сопротивлением 4 нагрузки и сопротивлени ми 5 и (J в цепи питани  сетки образует мост (фиг. 2), в диагональ которого вк.тючены электронный стабилизатор тока (катодно-след итий стабилизатор тоха) ц конденсатор 2.Between the transformer and the capacitor 2 is connected an electronic current regulator ZP, which is supplied with; 1 pulses of rectangular shape from the limiting amplifier of the VLR. A lamp voltmeter is used as a device for measuring the voltage at the terminals of the capacitor 2. The lamp 5 {6Ж4), on which the limiting amplifier is built, together with the resistance 4 loads and the resistances 5 and (J in the power supply circuit of the grid forms a bridge (Fig. 2), the electronic current stabilizer (cathode-trace Toha stabilizer) tc capacitor 2.
