Hi KNT,

It seems that your chassis is a 66, and the schematic is available on both Nostalgia Air and in our library.  Generally, if I am correct, Philco models are named after the chassis, with a suffix if the chassis appears in different cabinets (example, tabletop vs console vs chairside).

I am attaching the schematic from Nostalgia Air.  The diagram is also in our library, but I am attaching the Nostalgia Air diagram because it includes a chassis top view.

BTW,  Do NOT plug this unit in especially with the rectifier tube in place until you recap this unit, or at least replace the power supply filter caps.  The dried material on the top of one of those caps is indicative that it was likely a "wet" electrolytic and it is likely shorted.

I did not find this in our gallery but it is listed in the chart by Ron Ramirez (God rest his good soul!) in the Philco Library > Models > Set Index

Here is a link to Radiomuseum showing 4 different models using chassis 66. 
https://www.radiomuseum.org/r/philco_66.html

JRBlasde listed the models with suffixes.  There is a document somewhere that explains the cabinet type denoted by the suffix.  This radio was introduced in late 1933 for the 1934 and 1935 model years.

The cabinets are basically 2 types of "Baby Grand" (Cathedral or beehive style), "Moderne" (tombstone style) and "Lowboy) console style).

Although this is only a 5 tube radio, it should be a good performer due to the higher B voltages than used in the AC-DC "AA5" type radios allowing higher gain in transformer powered sets.  Hence, the use of this chassis in a full size console model (with the nice, bigger speaker).

It appears that your set is the 66BM "Moderne", very forward styling for the times (in the throes of the Great Depression).
