You probably can't find anything because a Model 740 is a Canadian model number. Your best bet for finding that would be to find someone with a set of Radio College of Canada manuals if you want a schematic, though there maybe someone out there who has the Canadian Philco factory service data. It is from between 1948 and maybe 1952 by the looks of things, that being said radio phono consoles from that era don't tend to have much collectable appeal, if that was something you wanted to know.
