I don’t see how the 38-690 antenna input is balanced; although it has the 3 terminals (red, black, and ground), the black and ground are connected together and are connected to chassis ground. This is how my unit is wired, and is confirmed on the schematic. The chassis is grounded for RF purposes through the Bakelite block line condenser to whatever side of the line that is the neutral (or external ground).
So explain how any balanced antenna would work (including the Philco) without a balun.
