All:
A friend got a 1977 Tyco HO train set. It comes with 4 or 5 cars, a 24" x 36" oval of track, but no powerpack. It's going to go to his grandkids. He's going to get it checked out at a train store, just to make sure the locomotive works.
Assuming that it does, what sort of inexpensive power supply / transformer would you recommend?
Many thanks,
George
