Is there a difference between NTSC and PAL CRT tubes?

Hi!

Are there any CRT TV aficionado here who can tell me if there is a difference between NTSC and PAL tubes? I know the shadowmask doesn't usually line up with scanlines and neither does it align with the "pixels" horizontally, so I would guess the tubes are the same. But are they?

I'm asking because I may be repairing an NTSC (Japanese) CRT TV and may need to replace the tube if I'm unlucky. As I live in Europe, getting an NTSC TV as a donor may prove expensive. It would be nice if I could replace it with one from a PAL device.

Thanks!

(I sure hope this is the right place to ask. I can't find any other place on the forum to put it. Repair maybe?)

No basic difference, shadow mask etc. would be the same.
The only potential difference could be the vertical deflection coils due to the 25/30 Hz.

I think you're confusing the (in)famous NTSC "Hue" control with phosphors. I see no reason for using different reds.

No I am not. Read the colorimetry sections of https://en.wikipedia.org/wiki/NTSC and https://en.wikipedia.org/wiki/PAL

Strange how your posts disappear. Trolling much?
