philco tropic model 42-760

> the green speaker wire goes to negative side of 15 uf
Wire color is not listed what I can tell you is that one of the field coil wires goes to the chassis the other goes to the negitive side of the 15uf cap.

>the wire that goes to resistor 77 and on to power transformer goes to negative of 15 uf
Yes

>wire that goes to resistor 16 goes to positive of 15 or 40 uf and the wht clip wire that goes to output transformer goes to positive side of 15 or 40 uf
Yes

>does the 40 and 15 still connect together at the positive side
Yes

> because in your earlier drawing they were connected and of course the negative side of 40 uf goes to chassis ground
Read post #12. I drew the the diagram wrong that's why I deleted it and redrew it correctly. Forget the first drawing. BTW the - side of the 40uf cap does connect to the chassis  the - side of the 15uf doesn't, it connects to 77, pt and fc.

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!
