Nor do I, but am sure he did.

When you state "no noticeable degradation in sound" you are likely falling into the trap of not noticing something that happens slowly over many months or a few years. The incremental change is small so you don't notice. If you track hours on your tubes (I always do so) then try a new set of power tubes after 2500-3000hr and you may surprise yourself. The new set should be burned-in for 50-100hr then the old set put back in and see if you hear a difference. Of all tube amps McIntosh, due to their design, is one of the least sonically impacted by aging tubes. A good thing for the owner's wallet.
