MCMElectronics has some inexpensive variable power supplies.

This one goes from zero to eighteen volts:

It is cheap and handy for a lot of stuff like this. I added
a second on/off switch so I can turn on the unit with its
original switch, adjust the voltage, then turn on the output
from my second switch. This saves a lot of plugging and
unplugging if you change voltage a lot.
