Info gleaned from Philco Service Bulletin #325.

The audio output transformer, pn/ 32-8120 in chassis mounted (underneath) and is next to the 37 tube by the power transformer.

The field coil on this 14" EM speaker is 1,100 ohms DC. The speaker is p/n 36-1523. The voice coil impedance is 5.1 ohms at 400 Hz. and has a hum-bucking coil to boot.

This speaker is also used on models 41-285 and 41-287.
