This circuit was found in an old documentation, being able to generate signals of frequencies in the range of 50 to 100 MHz. The components are of the 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...
