This circuit was found in Ferranti's 1974 transistor manual. The transistors are from the period and the frequencies generated are between 50 Hz and 2 kHz.
This simple inverter was found in a 1997 documentation. Its purpose is to apply a high voltage to a...
For this circuit, the polarity of the power input does not matter, as the output terminals will...
