This circuit makes use of a mechanical delay line to produce the reverberation effect. This is a '80s setup, showing both channels for a stereo system.
This interesting low current circuit uses only one diode to obtain a full wave rectified signal....
The circuit shown is from a 1993 documentation. It uses two FETs in an oscillating configuration that...
This circuit serves to prevent devices powered by 6 V from being left with a power cut. The...
