I'm going to be installing a Lionel fan-driven smoke unit. The ones with the rectifier built in for the fan.
I've always run them off of lower ac voltage, but in this case I have to run it off of 18 volts constant AC. I want to lower it down to about constant 12v AC.
Probably a stupid question, but what is the best way to do that. I've used resistors in plenty of DC circuit's, but never in an AC circuit. Will it resistor even work in an AC circuit? I tried a few and had no results.
