Who cares, it makes an image.

I'd love to find a 21AXP22 for my CTC-4, but they don't grow on trees. Meanwhile, a glass CRT lets me watch the set. Without viewing two CTC-4s side by side (one with 21AX, the other with glass), I'm not sure my uneducated eye could tell one from the other, anyhow.
Sorry, I don't have a good guess about the orange discharge inside your CRT. What's the condition of the CRT's aquadag coating? All in good shape and securely connected to ground? Does the dancing glow move in concert with arcing sounds? Or is completely independent? Phil Nelson Phil's Old Radios http://antiqueradio.org/index.html |

Is there a ground strap on the bracket that holds the crt ?
Sorry it was mentioned already by Phil Nelson . |

Shouldn't be possible, the shadow mask is spot welded to a frame which has a lip on it that extends back towards the electron gun specifically to prevent stray electrons.

One last question: does the display on the screen face change in any way when the orange glow is dancing? I don't have a theory about what it is -- just curious.

Tube's probably fine, just a bit weird.
Also the guns might "wake up" if left to run for awhile. |

Let the CRT cook for an hour. It came right up. Full steam ahead with the restoration. Already have good color picture but a lot of interference.

Well heck, you're already 90% there. Probably just needs a good recap and it'll be good to go.

Here is what I am working with. Heavy interference and bad purity.

Looks like bad alignment to me. If you turn down the color to 0, then adjust the fine tuning for best monochrome odds are a lot of that smearing/ringing will go away, and if you then turn the color back up you will not get near as good a color picture at that fine tune setting.
The alignment on my CTC-4 is total crap (thus why I put it to the side)...Color, monochrome, and sound all are at their best at different fine tune settings and there is NO compromise setting that allows two to be even decent simultaneously.
