If you add line capacitors, a ground connection to the chassis is no longer needed. Before adding the capacitors to my Philco 20, with no ground wire, only the strongest stations would come in. When I would connect a ground, many weak stations would suddenly come in and the strong ones would boom in very loud. After adding the line caps, the radio works equally well with or without a separate ground connection. I have another Philco 20 that I plan to add the line caps. I also intend to modify the interstage transformer circuit.
