This is the power supply circuit for the amplifier in the previous circuit. The source is adjustable and uses power transistors of the time. The AC transistor must be mounted on a heat sink.
In this circuit we show how to configure the LM3914 as a bargraph or moving point, supplying 10...
We found this circuit in a documentation for 1977 American radio amateurs. The LM336 integrated circuit...
This modulator circuit is nothing more than an audio amplifier that serves to modulate amplitude...
