amplitude sine wave is getting the amplifier loop gain just right. By using the 2N3069 JFET as a voltage variable resis-tor in the amplifier feedback loop, this can be easily achieved. The LM103 zener diode provides the voltage ref-erence for the peak sine wave amplitude; this is rectified and fed to the gate of the 2N3069, thus varying its channel
