long time ago, I built the files posted by Stefano but does not work . I do not know if I have wrong in the assembly.
The project is very interesting, the PCB is very small, someone could build it, maybe I missed the assembly.
excuse my bad english.

Hi . A better retrace of surf pi schematic with altium by me .
I also replaced old 2N3906 with BC327 and audio output transistor with
BC337 which is more available on the market .

[oxygen007m]

For those who interested in single layer pcb , I also have attached the
gerber file . There is not any error with pcb , so use it with confidence .
enjoy boys
