This circuit is from a Radio Electronics from April 1964. The circuit uses power transistors of the time, which must be mounted on a good heat radiator. Modern equivalents can be used.
The presented circuit is used in Power supply to increase the voltage output. The voltage output...
The frequency of the LC resonant circuit must be the same as that of the crystal and the JFET...
This amplifier can be used for public-address or other applications. Three transistors of the time...
