This circuit is from Mullard 1969 documentation. The circuit operates at a relatively high supply voltage and has a 10 Vpp output. The transistors are of the time, but admit equivalents.
An way to change the frequency of the previous oscillator (CIR112E) is to add a variable capacitor in the...
This circuit uses a JFET, which may be of the type BF244 or BF245 and a PNP bipolar that may be...
