I disagree that any TH6 is "near end of service life". It depends on the
condition of the individual beam.
I have 2 TH7's. One started as a TH6 I purchased new in 1971. I converted
it to a TH7. It shows no signs of being near "end of service life" -
whatever that is. They may need to have the trap caps and driven element
insulators replaced every decade or so but the rest is just fine.
I've often ponder replacing my TH7's but find it difficult to justify the
large expense of the newer generation of beams for the possible small
incremental gain in performance.
