Original poster: "RIAA/MPAA's Worst Nightmare" <mike.marcum-at-zoomtown-dot-com> Trying to find a 120/240 in and 0-560 out -at- ~7A and can't seen to find any used (new they are about $2k). Is it possible to parallel the primaries and series the secondaries of (4) 140v versions? Do the secondaries have to be isolated (more expensive and heavy)?
