Philco 19B Code 126: rewinding an open antenna coil, pesky volume drops
#9

I completed the rewind with AWG 40 wire.

The Nostalgia Air link notes the primary should be 27 ohms. Ron's (deactivated) blog suggests the original may have been AWG 38, which is about 0.66 ohms per foot at room temperature.

My rewound coil measures 85 ohms, so I may have overdone it a little and put on ~80 feet of wire when the original likely used closer to 40-45 feet. I've coated the coil with wax already to keep the fine wire in place, so can't easily remove turns.

Any reason not to just use this as-is?
