I suspect that in the future the ultimate will be the tubes
for Tektronix 454 and 455 scopes, possibly the higher end 7000 series too.

There really would be no way to fix one of these short of replacing just
the cathode, the gun is so complex.

And there is simply still no digital substitute for some uses for these.
