[mancave]

I have completed electronic restoration on a Philco 46-1209. The radio portion works very well and sounds great. I'd like to work out how to install a bluetooth input. This radio has a built-in phonograph, and before connecting a bluetooth receiver I attempted to feed signal from my cell phone earphone jack through the phono pickup transformer, but no sound came through. I then tried bypassing the phono pickup transformer, but that did not work either. I had connected right and left channels together through a pair of 39 ohm resistors and tested the output with a spare set of headphones to verify output. 
The schematic of the radio/phonograph is here http://www.nostalgiaair.org/pagesbymodel...013586.pdf
