...until one of those tubes loses it vacuum and you find it's either
unobtainable or costs $75 or more.

That happened with my 535 and its high voltage rectifier tube (5865?
Something like that).

Allegedly, though mine didn't have it anymore.

I now have a 7603, which is quite nice. A lot lighter than the 535,
and it has a useful bandwidth for ham radio purposes. Now if only I
could find a spectrum analyzer plugin for it that costs less than a
car... :-)
