Philco Cda 44-121 Ident & Info Required
#6

CanoeBear

Welcome. I have just compared the schematic of the Canadian 44 to the USA 41-300 and the chassis are basically the same, as other folks have mentioned. The cabinet is the same as the USA 41-315X and 41-316RX. I would call it the equivalent of the USA 41-315X because of the cabinet.

I only see one minor difference in the schematics of both: the suppressor grid of the first 7B7E (1st IF) tube connects to the AVC line - top of cap (31) instead of to ground in the USA version.

It is a 1941 model, apparently also offered in the 1942 season in Canada but not in the USA.

If Arran does not have the schematic, I think Just Radios sells Canadian radio schematics.

You could also order the 41-300 schematic from Chuck Schwark, which will have more complete info than the RCC manual has, just bearing in mind the slight difference in the circuitry mentioned above. Well worth the small fee charged.
