Hi Tom,
The .25mfd cap are wax/foil originally now days they get replaced with mylar or film caps (not electrolytic). As for your osc issues I'd measure the resistance of the four connection on the osc coil to be sure that they all have resistance to each other. Should pretty low like 30ohms or less. If not coils is bad. Also measure the resistance from chassis gnd to the stator of the osc section of the tuning cap to be sure that you don't have any more shorted plates. Measure it with all the way closed and then open should show an open circuit both ways.

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!
