I thought to myself, This set's going to have a great picture. I checked the tube before installing it. Zip, nutin, nada, not even a heater glow. I even started it at a lower heater voltage. Looked like it went to air, but no white on the getters.
When sent, it was packed very well and shipped by Fed-Ex. Both boxes were in good condition, so it didn't appear to be mishandled.
I don't think the tube was checked before it was shipped.

If the getthers are still normal, then perhaps it is just a bad heater weld. I'd consider getting something like a charged 80uF 200V cap connecting it to the heater pins and tapping on the neck with a screw driver....You have nothing to loose in it's current state.
