I'm still using a 25-year old Troller handheld throttle and a not- quite-as-old Rix handheld on a common rail system using 50-Watt AF transformers as power supplies. According to what I think I learned about Basic Electricity many moons ago, I should be getting about 3- Amps from the 15V constant voltage posts. Anybody care to comment? Also, in the useful techniques department, since my layout is still under construction and many things are temporarily temporary, I use a test light on the variable voltage post @1/2 voltage of one transformer as a "power on" indicator. I read somewhere that these old toy train transformers are one of the best power supplies available for handheld throttles and the like. I know they do a great job for me, and I have more 50-Watters warming up in the bull pen for additional throttles Bob The poll results are in.......
