This converter or inverter uses components that are still common. The transformer is the type found in old tube equipment. The power transistors must be mounted on heat radiators.
This circuit takes advantage of the noise generated at the junction of a zener diode of any type....
This low-frequency oscillator was found in a 1963 documentation. Capacitors determine frequency. The...
This configuration with FET and Unijunction can be found elsewhere on this site. The JFET admits...
