Staco Transformer Voltage

[rickpend]

Hello, I have what I believe is a bad transformer. it is a Staco transformer 023-1279. I think the secondary winding is bad. Does anyone have information on Staco transformers. it is a small control transformer and the voltage is not noted anywhere on the outside.

Basically, it needs replacement and I am looking to spec out a new one. Thanks!

What is this Staco transformer used for? Maybe you can just use the rest of the circuit to determine the voltage that was being supplied?
