hasn't done a production run yet. I'll try to light a fire under him. I have
four Polarises that would make nice homes for his boards.That probably wouldn't make a whole lot of difference. The real problems are

computer noise on the grounds and power supplies, digital noise coming in

Ciao, Paul D. DeRocco
Thanks for that info.
I'd be happy with a schematic and parts list (hand drawn on a cocktail napkin?). I've never built anything before where I had to source/make my own PCB, but beyond that I'm sure I could cobble it together . . . and I'm sure the good folks of this group could give me some suggestions how to go about creating the board itself.
Cheers,
