[Also in Division H3] The low voltage supply for a tunnel diode circuit (see Division H3) is the difference between the voltages developed across two Zener diodes D 1 and D 2 . The supply for the Zener diodes is obtained from respective variable resistors 51 and 52 and the low voltage supply is filtered by a circuit 4, 6.
