You can make a crude substitute for a variac by using a string of old style Christmas lights (the type with the C7 bulbs) wired as a dim bulb tester. Leave all the bulbs loose to start with, tighten them one at a time to bring the voltage up slowly, You may want to replace a couple of the bulbs with 25 watt for a course adjustment.
