No. Focus issues can also be caused by a problem in the tube socket,
or loose connection to the HV diode...

Oh, and re-reading the original post I see "A couple years ago, a
friend of mine brought over a Space Invaders to see if I could get it
working before he sold it on ebay." So is Matt still trying to get
his game right after a few years - before ebaying his friends game?
And people complain that I am slow (ducking).

I would run a jumper wire from the monitor chassis to the logic board
common and see if that helps. It sounds like a poor connection to me.
