"An old tube can measure perfect and be at the end of it’s life the next day."
That’s interesting. In well over 25 years of owning tube components (Friends also with similar tube equipment backgrounds) this hasn’t been the case. Test results correlated well with tube performance and tube longevity.
I’ve not known anyone who have had tubes test strong-very strong and then rapidly fail. @russ69 was this a rare or common occurrence? As others have mentioned above the Amplitrex is an excellent unit.
