< 1 the green speaker wire
The schematic doesn't indicate the wire color, but measure the resistance from it to chassis and if it is about 800 ohms connect it to the - side of the 15uf cap.
<2 the one that goes to resistor 77 and on to the power transformer
connect it to the - side of the 15uf cap.
<3 another wire that goes to what looks like a small power transformer in the middle of the chassis
Don't know I can't see it from here. Take a pic of this sm pt top and bottom and we'll figure it out.

Looks to be #16 15,000 ohm resistor @2w. It connects to the
+ side of either the 15 or 40 uf cap, it's the same connection.
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!
