No experience on early Zenith, just wondering.

I've checked the hold control and it seems fine, I've also disconnected every other connection to the grid on pin 5 (one at a time) to see if something was killing it.
The Cathode is on pin 8 and the .6 is very close to what Sams calls for .4 I think?
I suppose it might be a good idea to check the resistances against what Sams says and see if anything stands out.
