Morning !
Looks like it should go over the to pin 4 or 5 ( should be hooked together ) of the 77 mixer tube.
It's part of the oscillator feedback circuit. It's common on these set of the feedback winding to
rot and on open. Your wire may have been disconnected to troubleshoot the coil.

ps Replace your filter condenser both sections lest you want to replace both section of the filter the 80 tube and the power transformer later!

When my pals were reading comic books
I was down in the basement in my dad's
workshop. Perusing his Sam's Photofoacts
Vol 1-50 admiring the old set and trying to
figure out what all those squiggly meant.
Circa 1966
