I agree with Wally, use a 240-110 stepdown transformer then at least
you'll know the heater and HT lines are correct. No point in risking

I've already got a 110 v transformer for power tools, but it's a big
b***ard. And I don't want the faffing around of using one anyway. Also, if
I had to buy a smaller, more suitable one, I might as well just replace
the sig gen transformer with a 240 volt one - like all equipment of this
age there's plenty of room inside.
