Found in Radio Electronics from the 90s, this circuit is intended for analog TV applications of the time. The transistor used as well as the module are uncommon components today.
We found this circuit in an old American publication from the 1980s. Transistors can be...
The circuit shown uses the LM340 but applies to other regulators. We found this setting in...
This circuit generates signals that depend on resistors and capacitor, producing a tone in a...
