The same antenna terminal is used for AM and SW.
(getting out binder with 38-10 Service Bulletin to confirm) Yup...as with most 1938 Philco models, there are three screw terminals in back: RED, BLK and GND. BLK is connected to chassis ground as is GND. The RED terminal is used as the antenna if you are using a conventional longwire; if you were using a dipole such as Philco's High Efficiency Aerial which was available when the set was new, the red lead of the dipole lead-in connected to the RED terminal and the black lead to the BLK terminal.
It's resistor (11) that was changed from 70K to 40K. Yeah, 39K should be fine as a replacement.
