This is the power step of the previous circuit. Output transistors must be mounted on good heat sinks. The circuit is from documentation from the 60s.
We found this circuit in a 1986 Elettronica Pratica magazine, but the components used are common. As...
We got this circuit from Radio Electronics from July 1990. The circuit mimics the sound of the red...
This circuit interrupts the power supply when grounding is missing. The circuit is from an old...
