Hello Lennyski..........
I am using the MRC 130 VA's or Watts transformer model # AH501 and had it for 6 years so far no problems running the williams engines ( I have berkshire and sd-45) this transformer is a single trottle type and puts out "pure sine wave" AC. the berkshire pulls a 4 car 60 foot madison cars and a boxcar (both are williams). My williams engine's can motors never got pass lukewarm after running for 40 mins to a hour on my TINY 4 by 8 layout. Just wanted everyone to know....... SMILE
