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.
I found this circuit on a December 1976 Radio Elettronica. The Italian magazine no longer exists, but...
This power supply is not protected from shorts in the output. Output voltage is given by the...
Any power MOSFET that supports the current of the controlled stepper motor can be used on this...
