Another thing to keep in mind when using the piece of metal coupling to the line cord, you want to have a couple of feet of cord from the back of the chassis to the point where the metal coupling is positioned. Since the line bypass caps short the RF signal to ground, there is very low signal on the line cord where it enters the chassis.
By moving the coupling point a quarter wavelength or so from the chassis, the RF signal is at a relative maximum at that point.
I forget the exact dimension, but on the Philco's like the 48-482, there is a rather long wire to the antenna input which connects to the coupling point on the line cord some distance from the chassis.
