If the FM radio tunes it then there should be enough FM slop in the generator for it to work with TV audio.
Before you start with IF injection first try audio injection at the first audio stage grid. That knight generator should have an audio output you can use. If the set passes audio from the 1st audio grid decently then IF injection is the next troubleshooting step. If it doesn't pass audio injected at the 1st audio grid then troubleshoot the audio stages and make them work before messing with the audio IF.
We can walk you through audio IF injection if you end up needing to do it.

Excellent...I have a Channel Master Super Fringe (Sanyo inside I think) AM/FM I restored that has a great speaker and makes terrific sound for a 1962 tube set. I'll try using that and the Knight. Yes, I will probably need some seeing eye dog aid in crossing these audio output tracing streets! Thank you so much for the help. It is so appreciated as is everyone's input in this thread. Thank you all!
