Power transformer replacement??

[Tubejunke]

I have mentioned this before but I was a bit unsure. My RCA TCS-127 needs a power transformer. After much hope of this not being the problem I have come to the conclusion that it is. I borrowed a Megohmmeter and verified that my primary is shorted to ground. Along with at least one secondary winding. I stopped checking after that. I dont know how hard this is going to be to tackle. Not doing the work but getting the replacement part or having the existing part repaired.

Are there places that rebuild iron core transformers?

Are there places that sell N.O.S. or replacement transformers?

I have never had to replace any of my transformers so this is new to me. Any help or advice would be greatly appreciated. Here are the part #s on the trans: 970972-1-3
138012

The chassis # is KC534B
