1:1 isolation transformer and filter for Garrardzilla

I've been an advocate of speed controlled stability for my Garradzilla only using massive platter, but must say, to my surprise, this humble box made by my pal Francesco further improves sound... placebo or real improvement, dunno...

Sure, detailing improved... maybe less motor (micro) vibes due to cleaner 220V?

Mysterious, doubtful uncertainties... yet, good result.

Enough for me;-)
