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.
We found this circuit in an American documentation from the 60's. The transistors are made of...
The accuracy of this circuit depends on adjustments made with capacitors of small tolerances of known...
The figure shows how to implement an OR function with two inputs, using a relay. The relay...
