A little help Please
#17

Perhaps this will simplify it for you.
The HV is directly connected to the bottom on the output transformer, SG of the 50l6 (pin4), bottom end of 20 (1st audio plate resistor), bottom end of 13 which in turn feed the plate of the IF amp, bottom end of 10 which in turn feeds the plate of the 7A8 mixer, pin 5 of the osc coil, and the left side of 12. The right side of 12 feeds the SG voltage to 7B7, grids 3 and 5 on the 7A8 and is bypassed thru 11 back to B-.

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!
