Philco 39-7 issues

OK, so you have the antenna xfmr secondary (5 Ohms) open.

Just for the heck of it, trace these to actual leads on antenna transformer coil (shown at the left upper corner of the sch in Riders) and confirm the open.
Judging by the way it looks, the open is the 1-layer coil, while the "Universal" thick winding is the 40 Ohm one. If confirmed open, eitehr has to be rewound or taken from another radio (they do pop up sometimes).

You need to ohm out the pin 3 (the middle of the top 3 pins at one end of the bobbin) and the pin 4 (it is a single pin at the opposite end).

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
