This is the typical circuit of a local oscillator for a superheterodyne FM receiver. The circuit was found in a 1980s documentation and is typical of early and early receivers.
We found this circuit in an Intersil documentation. Temperature sensors are special components of the time,...
In the figure we have the way to reset (turn off) an SCR using a push button switch on a...
We can either supply this circuit with 12 V if we use a relay for this voltage as well as 6 V if...
