I'm not sure about what output transformer was used on the later model 112 chassis with the dual #47s, someone with the Philco parts catalog could tell you what number transformer was compatable with what. Since the late production 112 chassis is likely the rarest of the three versions it is more likely that you would find a 111 or early 112 then a late 112.
