RF or even switching transistors like the 2N2222 can be used in this circuit. The capacitors are ceramic and the frequency is determined by the crystal.
The LM318 is not a common component today. The circuit is suggested by National Semiconductor in...
Found elsewhere in this section, this circuit produces an output voltage approximately twice that...
This very high voltage (VHT)generator was found in a 1995 documentation. The transistors must be...
