Hi and welcome,
There was several different versions of the 89 chassis https://philcoradio.com/library/index.ph...-model-89/
I would have a look at the osc and see if the tuning the whole range. It's not uncommon for the osc coil to need a feedback
winding rewound. Use a pickup wire near the osc tube and another receiver to listen for it at the 89's dial frequency + the IF frequency.

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!
