This fuzz distortion circuit was found in old RCA documentation. Equivalent transistors may be used and the input signal must be at least 1 V wide.
With the coded activation of the relays, it is possible to control which of the 16 outputs...
The integrated circuit used in this application is not very common. Transistors and resistors...
This simple circuit makes use of neon lamps to indicate the voltage of a power grid. The lamps are...
