Hi Tim,
              Well, you can raise the voltage that way however your current
is limited by the current rating of your secondary.
So, you can get 10 volts but you are still limited to 30 amps.
Even though the transformer cranks out a peak current, that is only because
the ratio of cold current to hot, operating current is typical 10 to 1 for
some filaments.
We work with lots of high power tubes and the inrush is very time limited.
Some are constant voltage and self limit on the cold inrush.
One tube is 11 volts at 1100 amps and that is the running normal current,
imagine the cold current!
Mike
