Four choices:

- replace with "old stock"/used original unit. (ebay, etc...)
- replace all three with new xfmrs of suitable spec
- buy three "new" xfmrs from the German (iirc) company that is now making them. (or other supplier like that)
- reverse engineer the bad xfmr, and wind ur own (or have it wound for you)

Determining the turns ratio and freq resp, etc (the xfmr specs) isn't that difficult to do using one of the "good ones."
