RE: NO!!!!

Right. Overall volume may not change much. The character of over-drive & harmonics may change. IME, interchanging 12A(_)7 types have not caused any damage to any pre-amps or amps.

Putting a 12AX7 into a position that had a 12AT7 or 12AU7 which set to high bias idle point, may case the 12AX7 to get noisy or die sooner. Eg: putting a 12AX7 into a Fender amp 12AT7 reverb driver position. But, no damage to other components around this reverb area.
