Offhand, 20-25K sounds way too high, bit I have not done the math. It really depends on how much current is being drawn from the AC line.
One thing for sure-it will not boost voltage. If you have a 5V Xfmr, 5V is the most you will get when the pot is fully closed. You could use a 6V Xfmr, and dial it back slightly for 5V.
