TESTED AND WORKING

You are looking at A GREAT power step up from most starter set transformers. This one is 100 watts, two to four times more powerful than the transformers in starter sets. Has a great vintage 1950's look and feel. It was sold separately but was also the transformer you got in some of the high end sets such as those with Northerns, etc. This one has been tested here at Lone Star Trains and is doing everything it should. In fact, we just took it apart and serviced it for you. It was made 1949-56; then the 22030 took over.

This was also one of the heavier powered transformers included in some of the larger sets--maybe you need it to complete it. As you know, the 4B was made in three flavors: the square metal blue-gray one,
this square metal black one, and a rounded bakelite black one.

This one features:

  • 100 watts
  • 1957-64
  • Metal case
  • Power cord is in good shape
CONDITION: Tested and works. Has a medium hum (like most). Great to put with that set that requires the 4B. Unit is clean with some scuffs and some rubs in the white printing. Good cord. Just serviced. 

Whether you run American Flyer, Lionel or even Marx, you can use this AC power supply.
