I'd be real careful with the Variac on a SS. Someone else can chime in, BUT most SS stuff is a little picky about low voltage.
I've had KSA 100 MK2 and KSA 250, both were wonderful, units.
Both were recapped at about the 25-30 year mark.
The guy was in Sacramento CA. He charged me 500.00 labor per Krell
Including a 5.1 HT unit. The bill was 1300.00 with parts for a pair. 725.00 with parts on the 5.1 HT preamp/dac. (all class A, on the pre too.)
Still have the Preamp, sold the Krell amps years back. They will heat up a room, no problem..100, or the 250s, but all 4 was like an inferno in the summer...HOT! Worse than most of the valve units I owned.
Sure sounded good though, some of the best sounding SS I ever owned. They would best any of the class ds I own now. But the heat..
Regards
