Focus voltage at the yellow wire was 4KV. I lifted it and the voltage went up to just under 5KV.
Hooked that back up then lifted the black wire, and the focus control center pin measured between just under 4KV to just above while adjusting the focus control.
HV at the 2nd anode is 26KV so that should rule out the 6HS5 tube.
So at this point I think I just need the stick.

I can get a NOS ECG118 for $5.50 shipped. Do these have a shelf life, or am I good with NOS? I'm hoping Chester's still has one so I can just drive over and grab one.
