Trouble is 10 volt regulators aren't that thick on the ground, that
not being a typical electronics supply voltage.  However there are
readily available adjustable ones like the LM317T
(http://www.national.com/ds/LM/LM317.pdf ) where you set the output
voltage with two resistors.  These folks will sell you one for twenty
one cents with a buck shipping (but they have a $5 minimum order)

.

So you can pay money for the real thing or work for the generic, your
pick.  I can tell you resistor values if you need them.  You
shouldn't need the capacitors shown in the sample circuit -- the
gauges don't care about transients.

Yrs,
