Sounds like you want an X-ray transformer. These can be more than 100 kv,
and are high current, but short duty. What do you need it for?

I'm guessing you mean 600 Watt dimmer, and this won't work to well, as
dimmers chop part of the AC wave off to change the apparent voltage on the
load. As several people have mentioned, it is best to put in 120 on the
high voltage side, and measure the voltage on the low voltage side, unless,
of course, you don't know what the rating are at all, or which is high
voltage and low voltage. I would go with feeding a low voltage to it first,
like 1 or 2 VAC, and checking the output.
