Reese,
All suggested changes have been made. I had to use a 1k/1watt resistor to bridge the two b+ leads. It’s all I could lay my hands quickly.
9. 6Q7: pin 3 (the triode plate) goes to the interstage or input transformer that feeds the two output tubes. The other wire coming from that side of the transformer should get B+ to feed the 6Q7 from somewhere, probably from the + side of the second electrolytic filter cap? Check ohms between these two transformer wires: transformer should not be open or shorted.
Resistance between is…962ohms.
10. 6Q7: pin 8 (cathode) either goes directly to ground or to ground through another component or two?
Pin 8 is jumped to pin 1, which is soldered to the ground tab.
11. 6Q7: top cap (grid) should go through a cap to the center terminal of the volume control. Can't tell from the pix but this line should not be grounded anywhere or any signal will be shunted to ground and there will be no audio. Test: remove the clip from the grid cap of 6Q7, turn set on and volume up, touch grid cap. If loud buzz, audio section is working and something seems to be shorting out signal back to the volume control.
I did indeed get a loud buzz that quickly dissipated.
What next?

P.s. I am more than willing to take photos of any section or component you need to see.
