This power stage with two transistors was found in Radio Electronics magazine from October 1963. The transistors must be equipped with heatsinks and the supply voltage is 12 V.
The resonant circuit depends on the crystal frequency that can go up to a few megahertz. The...
This circuit is from the 1983 Intersil Databook. The display is plasma and must be excited by a...
This is a typical common emitter amplifier stage configuration. The transistor can be used...
