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 many 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.  It was made 1954-56; then the 22030 took over.

There were a few different versions of the 4B. The earlier  versions were square metal cases. This later version was made of Bakelite with that cool rounded front.

This was also one of the heavier-powered transformers included in some of the larger sets--maybe you need it to complete it.


This one features:

  • 100 watts
  • 1954-56
  • Bakelite case
CONDITION: C-6. Tested and works. Great to put with that 1954-56 set that requires the 4B.Much of the lettering is rubbed off the top. Unit does have a few scuffs and scratches...all visible in the pictures. Cord is original and is in good shape.


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