Ed, I followed up on your suggestion. I had reflowed the solder on the grid cap previously, so today I used a solder sucker to remove the solder for a better view. I found that the grid wire was broken off flush with the hole in the cap.

I used a trick that has worked for me before and doesn't require removing the grid cap. I tinned a strand of hookup wire, bent it 90 degrees, and poked it into the hole. I then thoroughly heated with the gun and flowed a generous amount of solder in.

Separately, I verified that all tube shields have good continuity to chassis when installed.

I'll test everything out later today and report back.
