Hello List,

Thanks all guys here, who asked me for circuit diagram, and about performance details. It was nice chance to correct some small problems with Signal Ground/Earth designation. I corrected SG/Earth designation and have added some comments, hopefully important for all, who are not
circuit designers by nature or profession.

Mike Virgiliev.
