Tubes are more rugged than that, especially if they aren't run on the ragged
edge of performance.  I tuned up an old RCA radio from the early '50s about
10 years ago.  I think it needed one or two tubes (out of five) replaced
when I bought it, but it's been running fine on the replacements (and the
remaining, possibly factory-installed tubes) since then, running for an hour
or two every weekday morning (it's plugged into an X10 appliance module,
which is switched on/off by a cron job on my Mac mini :-) )

(I have the rackmount version of your scope, plus one of the 545
models...picked up both of them at a swapmeet for $20.  The 545 needs just a
probe for it to be useful, but the RM585 came with some unusual plugin
that's not as useful for general-purpose use.)
