Hi good people,
I am in need of a 3140 schematic / service manual ! If there is any one that can help I would appreciate it- as it seems this manuals existance is slim to none .
Mike. I don't know if you are aware, but the service manual is available via
the 'Manuals' link at the top of these pages. I recently downloaded a copy, which includes a number of modifications made by NAD to various parts of the circuit, including the 'soft clipping'(which can be a cause of distortion), and phono preamp sections(which can suffer from instability). I had no problem
with the download(via FOXIT reader incidentally).
