That one looks rugged. I have 2 Variacs. My best recommendation is to get one with a VU meter...like the one you

It will smooth out things, I've tried it before, I use my variac at 115 right know so I get around 445-450 on the B+ with ****** PT, it smooths out everything....and my heaters are around 5.9/6.0 VAC so I guess its not so bad for the tube shredding....

Hi guy's just wonderin if any one could describe to me what the sound and feel difference would be between using the variac like Rockstah (anti cathode stripping way) and one of George's voltage dropping power transformer's would be ? Has anyone done/got both ?
