My Sparton Junior 410 is a 620 Console

[Phlogiston]

It looks like this cabinet was designed for a larger chassis (also). The wood has the channels where a larger radio could be slid into place, but a smaller frame was manufactured and mounted for the smaller 410 radio. This cradle is built of the same veneered wood as the cabinet, not finished, of course, so it must have been built at the cabinet factory. It has a nice metal Sparton model plaque on the back. It says 620.

This radio was a basket case, all delaminated and falling apart, but, my wife liked it. After a couple of weeks and some long and not inexpensive parts searches it looks and plays good. The worst problem was an open secondary on the CT windings to the grids on the 2 483's. I disassembled the transformer and fixed the open. I do not think that I ever would have found a factory replacement - for a reasonable price.
