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.
Found in documentation from the 70s, this circuit makes use of SCRs of the time. Modern equivalent types...
This circuit converts a range of input voltages to a corresponding logarithmic range. The...
