Well, you are to be commended for trying to test the effects of FR differences.
If you really want to equalize two amplifiers to the same frequency response into the speaker load, you would have to measure the FR at the speaker terminals and then EQ them so as to get the response within 0.1 dB within ranges where hearing is most sensitive. But that's not what you say those dealers were doing. So you don't really know whether the differences in the sound of the various amps could be accounted for by FR differences.
I doubt very much that most equalizers would be able to duplicate the the FR of a tube amp into many speaker loads, anyway, not even with the Cello EQ--but from your description, that wasn't tried. It might be close enough or it might not. A parametric might work. A digital EQ should be able to do so, though.
