There has been some looking for 24vdc power supplies
so I cast a holler to other OTs that seemed to remember
a possible source as seen in the following:

 Aircraft used 24VDC when I was in '67-71.

 Try Fair Radio in Ohio, or that place out in Omaha, which I will
 think of as soon as I send this off.

 Industrial power supplies are also commonly 24VDC. So you can
 check almost any industrial electric supplier.
