1924 hartman

Both audio transformers show reasonable resistance per section.
What is slowing me down is the lack of a diagram for this set. Not being sure what tubes were in it I am assuming 199's.
So I am currently not positive which tube pin is for heaters or plate/grid.

Have you tried the various magazines over on AmericanRadioHistory for a possible schematic? Most are searchable.
