Which is what that 28 volter is. But the simple choke input works very well too. But after writing that much earlier this am, I spent an hour snooping thru ebay, and was only able to find one 48 volt candidate, for a bit north of 100 USD, on the other side of the pond. Power transformers even at 36v ct. were non-existent. For a choke input, something in the 45 to 48v would be needed. Choke input filtering gives you nominally the RMS output in DC. South of 300 USD they don't exist. I've got a Hammond, Canadian made toroid here but from the size of the primary wire, I doubt it has the muscle to do it. The only label is under the translucent wrapper tape and very hard to read. I'll go see if Hammond still lists something that resembles this.
