Hi Paul, 

I attempted to reprint the section from the 1935 RCA "Red Book" for the Model 242 but the file is too big to post here. (Sometimes MS Print to PDF creates very large files.)  Therefore, here is a link to the entire RCA 1935 Red Book at the World Radio History website:
RCA-Victor-Service-Notes-1935.pdf

Here is the schematic and wiring diagram for the 1935 model:

Hope this helps.
