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.

Cheers, Gene Heskett
