Re: Getting the bugs out- a little help, please...



Original poster: "RIAA/MPAA's Worst Nightmare" <mike.marcum-at-zoomtown-dot-com> 

a dc resonant coil with next to no ripple and a stable rsg (uniform timing
to the microsecond) might work. simply use the same power supply for a
classic tc and a magnifier.
