No RF on 89
#7

Could be a couple of things:

It just doesn't like you. Heard you saying some bad words while you were working on it. No fix for this.

Dirty bandswitch

Lead placement. Leads around the osc coil may not play nice when too close or far from each other.

Faulty ground on rotor shaft on tuning capacitor. Or bad ground at chassis and tuning cap frame.

Check the wiring at the tuning cap that the connections are good and the wire is not failing.

Might try adding a turn or two to the feedback winding.

Weak mixer tube/dirty socket.

Happy Hunting & GL

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
Now I think I've got it!
