This circuit is from Mullard documentation from 1969. Transistors support current equivalents. Output transistors must be mounted on heat sinks.
We found this circuit in a 1975 publication. The power supply must be symmetrical, but other...
This circuit matches a high impedance input signal with a low impedance output. This circuit is...
When the power is on, the 1 µF capacitor charges slowly by R1 and P1 until then on trigger...
