Henry Radio can no longer supply transformers for their wonderful amplifiers.
I received email from Ted Henry in December of 2015 with the following suggested sources for power transformers and chokes. Below is Ted's reply to my request for information.
However, I also found this interesting source for used Henry Parts.
If all else fails you can contact Gary to have your old transformer / choke rewound. http://members.tripod.com/tubes_tubes_tubes/transformerrewindingservice/index.html
Here is the story on HENRY transformers and chokes.
Our original supplier (ECA then Magnespec) more than tripled our cost for transformers and chokes. We could not afford to stock the items and then mark them up for resale - all our customers would think Henry Radio is trying to cheat them.

Another source is:
Another Option is Harbach Electronics. They purchased the assets of the Peter Dahl company when Peter had to close it down. They can be reached at - www.harbachelectronics.com - (419) 945-2359
Another choice is to have the bad transformer/choke rewound
I'm sorry I can't supply the part any longer, it has been too many years.
