Hi,
What you are missing is the ground symbol next to 57. Everything to the left of the symbol is - voltage and everything to the right is +voltage. D and E are - bias voltages for the detector and the audio output stages. Easy peasy!

When my pals were reading comic books
I was down in the basement in my dad's

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!
