What the picture 1 shows is a current amplifier circuit made up of LF356 and so on. In the circuit, A1 is the backing amplifier while VT1 and VT2 (VT3 and VT4) can made up of the dual push-pull emitter follower circuit which amplifies DC signals with the frequency of 30 KHz and its output power is 1W. Vt5 and VT6 is used to protect power transistor when output circuit shorts. R1 is the sample and when the emitting polar current of VT3 and VT4 is 0.6A with the VT5 and VT6 on, VT5 and VT6 force the VT3 or VT4 to lower the base electric potential to protect the power transistor VT3 or VT4.
