Philco model 630 capacitor replacement
#16

OK. You have 4 electrolytic caps in your set. 3 of them are in a can (#67) and there is one over by that big power resistor, cap #52. In the original, two of the three in the can are connected with the - wires connected to the metal cover of the capacitor and the two + connections are made at the bottom of the cap The third cap in that can the + is connected to the metal cover and the - is connect to terminal on the bottom.
#52 The + connects at the bottom - to the cover.
If your new cap 3x10uf @ 450V all three - are going to be connected to the cover and the + at the bottom.
What that means is that section that connects to power transformer tap has the polarity backwards. (not good)
Use that section to replace #52 And use a separate 10 or 20uf cap to replace the backwards section. + side goes to the chasiss
- goes to the power transformer.
Make sense?

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.

Now I think I've got!
