This circuit is from the 1968 ARLL documentation. The MOSFET admits equivalent and the coil determines the operating frequency range being the plug type.
Suggested by General Electric in an old documentation, this circuit can use modern SCRs and the...
The frequency of this oscillator depends on T, which for the audio band can be a common output...
This circuit has a common configuration widely used in projects on this site. The transistor is...
