Do you know if the three tubes have red, green and blue phosphors, or are they white with the color totally due to the mirror coatings? I can't remember.

Thanks! This set is the reason I asked you about the pictures you took (and the reason I mentioned it in the OP)

If I find the peeling in mine I wonder if it's worth calling around to local glass shops to see if any of them do dichroic coatings? Kind of a weird ask, but I can try...

The CRTs are actually R/G/B colored phosphor, they're each individually marked with their respective color.
