This 12 V to 110 V inverter with 100 W was found in a 1977 Signetics manual. The transformer must be rated according to the desired power and the output transistors admit equivalents.
This circuit is from a documentation from the 70s. Thus, the original transistor no longer exists,...
The frequency of the signal that this circuit passes through depends on the voltage set in RV1....
This circuit has a type of bias called "virtual earth" providing good gain, given by R2. The...
