Further research has indicated part of the information I gave you previously was incorrect.
I was thinking of UK model 55, not 255. The 255 is a later model and is a battery operated receiver.
Model 55 is a TRF set, like the USA model 50; but it has two bands (LW and MW). It uses the same tubes/valves as Model 50 (three type 24, a 47, and an 80).
Model 56 (and Model 256 Radiogram) is similar to USA model 52, with two distinct differences: It also has two bands (LW and MW), and it uses 6.3 volt tubes! Two type 36, a 44, a 42, and an 80.
For those of us in the USA, that begs the question: Why didn't Philco use 6.3 volt tubes in Model 52?
My thought: Philco had already designed Model 51, 1932 was the worst year of the Great Depression here, and so it was easier to slap a new model number on an old chassis and make the 51 become the 52.
Dave, if you need service info, I have it...let me know.
