Emerson question - Phil27 - 09-06-2024

http://www.nostalgiaair.org/PagesByModel/795/M0004795.pdf

I am working on an Emerson 131am and was wondering why someone has attached a wire to the 6A7 tube grid cap. It appears to act as the antennae. There is no external antenna connection on the radio.

The radio works but needs an alignment because it picks up the same station in more than one spot on the dial. I’m new to this hobby and am not sure whether to leave it or where it should go if I have to relocate it.

All advice is always appreciated.

It is possible that the antenna coil is open.
It is also a known effect that the cap of the pentagrid, if touched, will act as an antenna. Which is still not a cure for open RF coil.
