Not exactly. Tube life is like 1/2 a bell curve. At 75% the tube may fall off good readings fast without warning. A 75% tube also can sound a bit soft losing the great sonics of a newer tube. So you would be better with a true 5751 vs a weak 12AX7.
BTW- I do not buy used tubes. I do not know what I am getting. The tube can read good today & fall off to weak in 500 hours use or less.
