I have been a busy boy today. I finished the power / final amp end of the chassis. I ended up modifying it slightly to accommodate the switched potentiometer type tone control. Other than that it is as the schematic and diagram show. I also drew out a much clearer (I think) diagram showing the connections on that end than the diagram in the original Philco notes, or the Rider manual. Here it is:

If you ever need to convert a radio from the switched type of tone control to one which uses a switched pot, I based it on the information found in Everybody's Radio Manual, pages 114 & 115. This book can be found in the library on this site, here is the link: https://philcoradio.com/library/index.ph...receivers/
