This circuit is from Mullard documentation from 1969. Transistors support current equivalents. Output transistors must be mounted on heat sinks.
I got this circuit from a magazine in 1967. The magazine no longer exists, but the circuit that...
This circuit is more elaborate than the previous one, employing an integrated amplifier circuit of the...
We found this zener regulator in a 1978 radio amateur documentation. The operational can be...
