That radio was made in 1945, and is a very common transformer operated octal tube set. Look for an RCA of around the same year, and tube line up to download. Should be close enough to help you.
Just emailed you the service data for the RCA A-1.

:I recently acquired a Canadian RCA model A1 and I cannot find the schematic here. Where can I find a schematic to download? Does anyone here have a scan to email? cheers
