We found this circuit in American documentation from the 1980s. Transistors can be of general use. The frequency range of the generated signals ranges from 500 kHz to 10 MHz.
This high voltage regulator uses only two passive components. The output is 100 V, but replacing...
The circuit is from the MC1539 manual, an operational one close to the 741. The transistor admits...
This is the transceiver circuit in a Knight kit sold in June 1964. The 5-transistor circuit...
