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.
This circuit is from an English publication from 1978. It generates random binary numbers when we...
We found this circuit in a Poptronics of February 2000. We can do its assembly using 4 1N4001...
Found in American documentation from the 90s, this circuit uses a GASFET of the time. The circuit is...
