This circuit is from Mullard documentation from 1969. Transistors support current equivalents. Output transistors must be mounted on heat sinks.
This circuit is used for cable checking. We found it in the Radio Electronics magazine of December...
This input stage has unit gain but a high input impedance and low output impedance. The circuit is...
Found in a 90s Popular Electronics, this transistorized circuit generates pulses from 2 Hz to 50...
