This circuit was found in a 1967 Delco Radio documentation. The circuit has an input voltage of 250 V and the load current is 2 A. The transistors used are from that time.
In this oscillator a phase shift network formed by C1, C2, C3 and R1, R3, R4 determine the fase...
For inductive loads we have the configuration shown in the figure. Note that the optical coupler...
