In Reply to: If a tube is broken in, does the sound slowly change even though... posted by Steve Parry on May 11, 2012 at 15:20:54:
I always recommend keeping a back up set of tubes on hand.
Not just for replacement in the event of failure, but to pop in after every six months or so.
I've found that a tube can still measure OK, thus meeting the manufacturer's estimate of longevity. But there is a difference between working OK and sounding more alive and cleaner.
If a new, unbroken-in tube bests a used, but functioning tube, for me it's time to throw away the old one - or put it aside as a back-up in case of a catastrophic failure. This subtle degradation always seems to occur well before the manufacturer's stated tube life ends.
IMO & IME, of course.
Best regards,
