For your consideration is this Lionel LLC multi-control transformer collection. There are four multi-control transformers in this collection showing different strengths and amounts of power they can put out. The first one is a type 1033 90watt 115volt 60 cycle transformer. The next is a type-KW 115volt 190watt 60 cycle transformer. The third one is a No. 309 115volt A.C. 25 watt 60 cycle transformer and the last is a No. 1239 110-120volt 50watt 60 cycle transformer. The condition of these transformers varies; the type 1033 is in the poorest condition, with the cord needing repair; the other three are in good overall condition, with no obvious signs of damage. The measurements of these transformers are 3 1/4" x 3" to 7 1/2" x 7" x 7".
