Actually two of them on eBay.
Some of you may remember me posting about a
506 that I thought was a mash up of two sets, guess it isn't, both of the eBay sets have the Delco TV-71 number on the bottom of the case but 508 tube charts inside.
The S-10-48 can't be the date either unless all three were made on the same day, unlikely I think.
The knobs are different than the usual Hallicrafters as well so I wonder if they are the Delco knobs?
Maybe Hallicrafters had a bunch of left over Delco cabinets and knobs?
In any case maybe I should be restoring the TV-71 cabinet instead of the 506 one.
Anyone have any of those knobs floating around?
