This circuit generates signals whose frequency depends on C1 and C2. JFETs are common types like BF245 or MPF102.
We find this circuit in the 80's own component manual itself. The characteristics of the circuit...
We found this amplifier with high input impedance and low capacitance, using FET, in a...
This circuit was obtained in a 1979 magazine, but it can be easily assembled today, as the...
