Dual-rail +/- 15V supplies used to be very common. When I first started with electronics all op-amps ran from a dual rail +/- 15V supply. It is only relatively recently that single-rail supplies have become "normal" -- atp If you can't fix it, you don't own it. http://www.ifixit.com/Manifesto ------------------------------------------------------------------------------ New Year.
