That's exactly what scott did...and also myself.
In his case, he applied exactly 10 vac from the variac to the paralleled
primary's..... with secondaries temp disconnected from each other..... and
both connected to nothing.
With normal 240 vac applied, sec is 5300 vac. That's a 5300 / 240 = 22.083
turns ratio.
With 10 vac applied, xfmr #1 has 220.83 vac. Xfmr # 2 has 221.6 vac
That's dick. 5300 vs 5318.4 Gimme a break.
