Hello to everybody.
I'm making a homemade metal detector, I have the xr-71 schematics.
But I cannot find the right pcb board to print.
If someone has it, I would be very grateful if you share it with me.
schematics
I also found discrepancies on what is the right amount of 4700uF capacitors, as can be seen in the image.
This is the most accurate board I could find. However it I don't think this one could be the correct pcb board.
And to finish, just want to say that if all else fails I'll use logic.
thanks and regards
