This circuit is suggested by General Electric in 1966 documentation. The Triac must match the engine. The resistors depend on the triac's sensitivity to firing.
This circuit was found in a documentation from the 50's. The transistor is made of germanium and...
Here we show a configuration in which we have a control voltage applied from a voltage divider, which...
