It is what RCA called a "capacitor pack" containing two capacitors and two resistors. The parts are C53, C54, R23 and R27. The components are part of the set's bass compensation circuit. One resistor-cap combo connects to the "Voice-Music" switch that is also part of the on-off switch as well as to a tap on the set's volume control; and the other two connect to a different tap on the set's volume control.
See partial schematic below, also the sketch showing internal connections and color of leads coming out of the can. In the partial schematic, R24, R25 & R26 comprise the set's volume control.
The original RCA print of the schematic and under-chassis drawing was shrunk considerably to fit on one 8-1/2 x 11 inch sheet when it was originally printed back in 1935-36, so that the quality is very poor as you can see above. But this should at least help you out.
Yes, the interstage transformer is definitely a replacement. Mine fortunately still has the original, and is still working (knocking wood).
