Hi Tom,
Next I would check the resistance of #28 both pri and sec. Both should very low. Connect your ohm meter to the stator of the tuning cap the osc section and measure the resistance. Switch must but set for manual tuning. The PB are a separate tuned circuit so if the bcb osc coil was bad the PB should still work. You may need to adjust the ant and osc trimmers if the set came from out of your area. Maybe a switch issue.
On #28 the winding that has the hv on it is the feedback. All the other windings are the tuned circuits for each band.
>Now how to get it going?
Now isn't that the $64 question! Just keep chipping away at it till you find the ultimate cause. It can be really repetitive....
>I might find specifications for those coils?
I don't think they are listed anywhere.
>Correct me if I'm making bad assumptions here.
I hope so cauz the osc coil is a pita. Have to do some more troubleshooting.

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!
