This circuit transforms 0 and 6 V signals into -4 to 10 V signals and can be used in a shield. The circuit uses transistors that are still common today.
I found this circuit in an English magazine from July 1982. The circuit is still viable because all...
This 75 W power supply was found in American documentation from the 1980s. Transistors can be...
This simple transistor amplifier is from 1982 documentation. The output transistor must be mounted on...
