When the cabinet was built as a complete radio, Philco (1936-37) was still making their own speakers and transformers in-house. After a long strike in 1938, Philco began buying more parts from outside sources and building less of their own.

I have never heard of "Inca" transformers, and Philco would not have used them.

None of the components inside your cabinet are Philco components.

Oh, in case you are curious about how this cabinet originally looked, it was one of the two sets in the links below:
