I am looking for a power transformer for a 15 tube Zenith. In 1937 Zenith made 6 15 tubers, all with the same chassis. The part number is 95-447. I also want to buy the power choke from the same chassis, part number 95-442. I have a working transformer and choke but I am restoring this for my mentor and he wants it back to original parts if possible. Thanks.
