Thanks for your informative reply. I had located a schematic for the exact model on Nostalgair but it is almost like a postage stamp with almost zero detail.
I too had to laugh at the dire warning at using tubes other than those by Crosley. They did not mince ther words in those days, even the warranty card is very direct.
30 days with all kinds of conditions and if you don't send the card in "tough luck".
I may have located some decent documentation from "Just Radios" here in Canada but not sure as yet.
Here is a pic of the schematic:
