I recently purchased an AC/ DC hobby transformer for trhe lights and accessories on my Lionel train layout. Its AC output is 19 volts and not variable. The Lionel accessories and lights work with the full votage supply, but I would like to be able to reduce the voltage to prolong the life of the bulbs and motors in the accessories- without buying another transformer with variable AC voltage. Can i buy a suitable potentiometer from Radio Shack or a Triac dimmer from a hardware store to regulate the voltage?
Any guidance would be appreciated. Thank you.
