   I have had some luck using old soldering 'guns' as a transformer for a
RSU.
Remove the tip and attach the wires to hand piece and ground to the two rods
that would hold the tip.
If you have too much current try the lamp dimmer on the AC input.

Old guns of 100 - 250 watts can be found at garage sales and hamfest for a
few dollars.
