Dude, just $#!^can the offending tube, and move on!

Its not *four years*, but only the ON-time in four years.

You living on some island where tubes grow on trees?

Yikes!!

a) If the tube was Chinese, 6 weeks of "on-time" would be a lot in
some cases.
b) Current-production tubes are readily available. Not for free, and
one may vastly over-pay, but it is not as if it were a 19T8 or some-
such.
c) After determining that the equipment itself was not at fault, then
yes s&*t-can the tube and move on.
