Philco 600 schematic (different versions?)
#3

How do you know what the value of a given part is? Are you reading the color code or marking on the part? Or are you using a capacitance meter to read it? Just reading it with a meter may just indicate drift not necessarily a change from the factory. It's not unheard of for a set to have service notes from the factory depicting changes. Agree with Rod go with stated values on the schematic if there are issues they can be sorted as it comes together.
The only one that I see that is fairly different from the original is the 510 mmfd cap in the osc. It's controlling the feedback for the oscillator. All the other seem to be pretty negligible.
I would very interested to read the resistances of the windings on the ant, field, osc coils, and the output transformer. Some of which look like they have gnawed on.

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.

Now I think I've got!
