Kein(e) Ein on this one :-)
Yes, modern AC mains voltage, according to the prevailing wisdom on the Entireweb, runs quite high. Thus I figured 127 would ease the stress on that Telefunken EL84 and its buddies :-)
Not entirely coincidentally, I got Mrs. H a Kill-a-watt for Christmas (she was
thrilled) so that we can measure AC line voltage, power consumption, power factor, all that stuff. It seems like a cool gizmo; hope it's at least moderately accurate.

I'll add a fuse and try to Variac this sucker up soon (maybe tonight; Mrs. H has a meeting tonight).
