The pincushion transformer pictured has a Warwick Electronics part number. With the "80-" prefix, it identifies it as a transformer. It would be interesting to see the part number on the Vertical output transformer and the audio output transformer - the transformer complement would lead to a Sears/Warwick chassis schematic (528.XXXXX chassis). Thordarson has a neat matrix that shows transformer part numbers vs. chassis. Could be useful.
It's not a ATR, Conar, or Heathkit, so maybe NTS, Devry?? Even Andrea, with their chassis that could be slipped into a custom cabinet, didn't use Warwick parts.
One thing is for sure - that is one puzzling TV chassis.
Cheers,
