We found this circuit in a Radio Electronics from October 1963. The circuit uses an output transformer with a center tap. The trimpot is adjusted for higher gain and lower quiescent current.
We found this circuit in a 1976 FET documentation. The circuit can be used to oscillate at other...
This oscillator generates a 1 kHz signal, using an old germanium PNP transistor. The circuit was...
We found this circuit in a European publication from the 1980s. The circuit uses germanium...
