This oscillator with emitter follower was found in an American documentation from the 80's. The circuit generates 100 MHz signals and the transistors admit modern equivalents.
This circuit was obtained from HAM Radio magazine in an 80's issue. The FETs are types of the time...
We found this circuit in a 1981 documentation. The circuit can still be easily assembled, as it...
This low noise audio amplifier stage uses only one transistor and has a high enough gain to...
