Antennas and Grounds and...
#4

Many thanks, let me digest all that!

It's a Philco 655 in a 645k console. The 655 has AM BC, SW & police bands.

Schematic is here, yay, but I haven't found a manual yet. It has a single clip each for ant & grnd, and screw terminals for red & black. These are all grouped together on the schematic.

House ground is of course bonded to a ground stake, so would any hum in the house ground be due to proximity to the AC wires, yet not be strong at the ground point itself?

Polarized plugs etc: Obviously the radio is designed to function with a nonpolarized plug, but it sounds like some thought is needed before connecting chassis ground to house ground. Thx again!
