You can always use your old 120 volt variac in a 240 volt circuit. Hook up
the 120 volt variac to L1 and neutral of a 240 volt outlet. Take the
variable voltage (hot leg) out of the variac and tie it to one leg of the
input to your transformer. Take L2 from your wall outlet and run it directly
to your transformer on the other input terminal. When you apply power, the
transformer  will immediately see 120 volts. Output will be variable from
120 to 240. I did this for some time on my 19kv 4.2kva  transformer, until I
found a 0-270 volt 28 amp Powerstat variac at the local Junkyard for $50.00
. I spotted it in a large metal cabinet. Asked how much they wanted for the
big dimmer. Don't underestimate what you might find in your own back yard!
