Work of the circuit
The circuit consists of power switch S, transistors Vl and V2, resistors Rl-R3, light-emitting diode VL, potentiometer RPl and RP2, capacitor C, the output jack XS and pulse transformer T. (It is showed in the picture 9-2.)
When the pulse therapeutic apparatus is working, the shining frequency of VL is same with the frequency of low-frequency oscillator.
Change the value of RP1 to change the frequency of low-frequency oscillator.
Change the value of RP2 to change the intensity of electrical pulse.
