Can a transformer be replaced?

I had a strange accident with my amp. While it was being shipped to my new home the transformer came loose from its anchor!! and bounced around inside the amp. The anchor was in the center of the transfomer and somehow they became separated. Anyway the amp no longer powers up. I took it into a repair shop and they said that the pvc coating of the transformer windings had been damaged and the transfomer might need to be replaced!! Does this sound right? Any idea where ome might get a transformer. The amp is a carver so the company is unlikely to help. Thanks for your help
