Larry,
Yes your pics does "muddy the waters" as they show a 6 tube chassis with the 53AS tag on a 8 tube chassis? I suspect that in 1942, war shortages, they had a 53 console but no 6 tube chassis left over so they stuck an eight tube 54 or 56 chassis in the console but still added the 53 metal ID tag and sold it as the 53AS. You may be able to identify your correct chassis model by comparing the tubes used with the eight tube schematics!

Yes it's rather bizarre but what you mentioned makes consummate sense. There was rationing of many items especially electronics items during WW2. A manufacturing deadline but no way to fill it conventionally so in goes the 8 tubes radio instead of the six tube. Will have to hunt through the schematics and see what I can find.

Does anyone know if Philco Canada and US shared designs at all after 1938?

Thanks

Larry

They did quite frequently, but they regularly assigned different model numbers to the Canadian versions of the U.S models. If that is an eight tube chassis where is the eighth tube? The RCC manuals show completely different chassis with seven and eight tubes, the eight tube models used loctals for one. Could you take a photo of the chassis from the top to show the layout?
