How do the getters look...Nice and silvery?... Thin enough to read a newspaper through?... White? Does the whole gun light up purple, or just between the elements where the beam is passing? How does it test for emission?
I think that every tube leaks, but glass tubes leak very slowly. Likely spots are where the wires pass through the glass, and perhaps around the HV button. When you re-gun the tube, you get new feed throughs at the base, and as a precaution, a little VacSeal or diffusion pump oil around the HV button can't hurt.
