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.

NOS usually will work, but most vintage parts are selenium rectifiers so reliability isn't guaranteed.
I typically try to keep 5-20 of these modern parts in stock.

I usually put 2 in series in focus applications to ensure the PIV rating isn't exceeded.
