Work of the circuit The circuit consists of power supply circuit, a square wave pulse oscillator, control circuit, pulse peak oscillator and pulse voltage output circuit. (It is showed in the picture 9-11.) Power supply circuit consists of Source switch Sl, battery GB, filter capacitor C3, current limiting resistor Rll and the power indicator LED VL1. Square wave pulse oscillator consists of Resistors Rl-R4, capacitor Cl, C2 and transistors Vl, V2. Control circuit consists of Control switch S2 (S2a, S2b), the transistor V3 and resistors R5-R7. Pulse peak oscillator consists of resistors R5-R8, capacitor C4, C5, LED V ashamed, diode VD, transistors V4 and pulse transformer T, winding Wl, W2. Pulse voltage output circuit consists of T’s winding W3, resistors R9, RlO, potentiometer RP, output jack XS, XP and plug electrodes a, b.
