This oscillator for the fifth overtone of a crystal was found in a Radio Electronics magazine from May 1970. Transistors are RF types, and the transistor determines the maximum frequency achieved.
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...
