These transformers have the Part # UET114 from Universal Enterprises, Inc.
From what I see on the internet, they look like universal transformers, 24 volt.
On one side it has WHT/BLK/RED/ORG wires. On the other side they have
BLU/YEL wires. The actual body is approximately 2 1/4" x 1 3/4". Please to
to the WEB site for information (I don't know anything about specs.)
