I am guessing the transformer did not sacrifice itself.  It is more probable it was put to death by a downstream component.

Before you replace the transformer, you should thoroughly test the rectifier and filter capacitor.  My first suspicion would be the capacitor.

 

A fuse would have been a smart move. I replaced the rotten original power cord, but had neglected to add a fuse . Pretty dumb for a safety engineer. I'm not certain where the circuit fault is, but the transformer sacrificed itself to protect the cheaper downstream parts.

Thanks for this information, I will start looking into obtaining the components.
