Hi Davecoup,

Having looked at the 37-650 schematic, I don't think that the chassis is a 37-650.  There are too many tubes.

It may be a 16 (ca 1934-1935 based on the following Tube diagram from the Philco Library, posted by Nathan Slingerland:
   

If you search the Philco Library for 16, you will find several tube and chassis labels.  Search the service info here at the Phorum and you will find the schematics.  I will put them here for your convenience:
Codes 121 and 123:

Codes 125, 126, 127:

There are 2 iterations of this chassis, codes 121, 123 and Codes 125, 126, 127.  The main difference being that the former has a separate AVC tube and the Latter has an RF Amp. Both have separate Oscillator and Mixer tubes, and both have a triode-wired Class AB2 AF Amp that likely puts out at least 10-15 Watts.  Therefore, this thing is high end and kicks @$$!  Perfect for a Radiobar, except that if it kicks @$$, it rattles glass.

*****************UPDATE********************
Klondike98, a Supermoderator and much more knowledgeable than me thinks that this a 116. Tee 116 is similarto the 16 and came out in 1936, the year that Radiobar switched from Gilfillan to Philco radio chassis. However, Radiobar did install radios to Customers order because the Gilfillan was not high end.
