This inverter circuit with transistors provides a voltage of 300 V from a 12 V supply. The current, with the original transistors, is only 55 mA. Transistors must be mounted on heatsinks.
This high-gain digital amplifier uses general-purpose transistors. The supply voltage is logic...
We found this circuit in the March 1993 issue of Electronis Now magazine. The circuit uses common...
