Chris,

Sounds like your crt is asleep. IF it was my set, I would get the chassis up and running so I could power it under real world conditions, to see if the crt is any good. If it turns out that the tube is under vacuum and you do NOT have the dreaded purple glow, then I would use the Beltron to wake up and CLEAN the dirty cathodes to bring back the emission.

Or... if you have a hand held tesla coil, you could also see if the tube is gassy by applying the coil to the neck of the tube. No purple would indicate a tube under solid vacuum, and then I would proceed to the Beltron cleaning to wake it up.
