I tried one of the Radio Shack multiple voltage converters on my Deluxe power feed and it worked great twice and then it fried, it was 1 1/2 v to 12 v but 300ma. The original was 3-5-6-7.5-9v and unknown milliamps and I belive also from Radio Shack, can anyone tell me a model number or brand to buy tomorrow and or what amperage is needed for the Dayton gearmotor.--Thanks--Leonard
