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.
You can change the output voltage of a fixed 3-terminal regulator using a zener diode. The voltage of...
We found this circuit in an old documentation from the 70s, but it can be assembled with more...
The SCR MCR1000 MOS is a rare component today. It is an SCR with MOS field trip, requiring a...
