We carry a limited number of choices in new transformers, because most available units are not suitable for the power needs of the larger scales (S, O, and G scales). We have experience with the following units, but they are not all easy to keep in stock, so it is wise to inquire before you order.  In addition, you will find original used American Flyer and Lionel transformers on the "TRANSFORMERS " Sales Category inventory.

Used American Flyer transformers can range from small 25-watt to 40-watt units, suitable for dedicated use running accessories, or small circular or oval layouts with no accessories attached, to large single or dual units with up to 350 watts of power.

Here are some examples of original A.C. Gilbert American Flyer transformers.
