I've heard over the years of some amp builders floating the filament
transformer. I was
told that you isolate the filament transformer from ground and add two chokes
in the primary side with bypassing. Since the primary side is 115V or 220V the
amperes demand would be much less on the primary side. Looks like any RF would
be suppressed greatly by the filament transformer and you wouldn't need a lot of
uH in the primary chokes to finish the job. Has anyone tried this???
