Was on the HAMMOND web site the other day and saw they have a line up of audio transformers. W9AC references them through a reseller. Just saw that.
FWI they are also making Dahl transformers for many old amps and rigs.
They make some Dahl iron. They had a problem where they couldn't get all the designs off a hard drive Jeff had supplied (the original purchaser of Dahl after he went SK). Those designs I believe where finally able to be deciphered. They where making all his iron for a period of time. Then they dropped some (a lot) of them again.
I believe Hammond doesn't want to compete with inferior products that are available today. EPD is supposed to be a Dahl substitute, but they aren't. They make voltage, they make current. But they sure don't make the KVA the original Dahl did.
