refurbing these items.
Some of the late-20s+ top-end receivers match specs with the latest -- physics remaining the same. Crosley, I fear is a notch or two lower on the scale. (And, of course -- the program material '09 would be AM radio or in some cases, short-wave. So I guess you'd just look at the restoration, for your satisfaction.)

Don't know any of the ilk, currently. Would think eBay would have a bunch, though probably sought after by his cohorts, too. Were I besotted, I think I'd try rummage sales in small towns -- since no one knows anything about the techno, nor what is desirable amongst those who do: one might snare a E. H. Scott for a song.. or Crosley, Emerson et al. By eBay time, it's too late.

For electronics types, it's fascinating to see the design innovations of the top-line super-receivers, in a day when general parts were so rudimentary.
Have seen on web some early parts catalogs. Each high-end receiver is a textbook for young engrs (back when we had those.)

Luck to him. (I expect that someone will have a Tek 5xx series vac. tube scope operating in 2050, if perhaps.. way-back in the cave with the solar powered inverter?)
