Why did Philco use one or two 117Z3 rectifiier tubes in their AM-FM radios?

Have you seen the assortment of tubes used in the 40-190? I think it is 4, 6 ,octal and loctal. .When you can get a 42 (6F6) or a 41 (6K6) as a 6-pin or octal, they must have been using up old partsm to use the 6-pin tubes and sockets. Makes me wonder about the date codes on the OEM tubes.
