I wonder what they did to the audio circuit, as the Philco's didn't use an audio output circuit. They transmitted the audio to a Philco radio, around 8mhz. They must've converted the AM audio to slope detection.
Looking forward to more information on this set.  |
Only the small 6" table set didn't have audio circuits installed. The 1938 MIL set had audio as did the larger 1942 10" console with radio.
The 6" table model I have had audio added around 1942, for some unknown reason Philco decided to use their own version of the 6V6, a 6V5 for the audio output.
