Philco 116B No radio reception
#16

There are three connections at the bottom of 101.
One connects to the junction of 98/99. Internally it connects to the plus side of the 8mfd cap. It has about +300vdc and is probably is the red one.
One connects to chassis ground internally is connects to the + side of the 10mf 50v cap. Probably silver, unfortunately the schematic doesn't list the color on the bottom of the cap.
The tab on the side connects to the tab on the tab on #100 (the other filter cap) and the center tap of the high voltage winding (B-). Internally it's connected to - side of the 8 mf and the 10mf at 50v. It has about -20vdc at this connection.

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!

OK. well like I said I have the capacitor "restuffed" except for the negative leads which I still need to get the negative leads of the new capacitors attached somewhere.
