There are no "technological means". Professional tuners of a number of
instruments tune by _ear_ after tuning a single note (which is
independent from temperament) to a reference. Of course, organs are not
really tuned equally tempered even now, but that's not because of a lack
of competence. Accordions are tuned by ear by good tuners, and those
_are_ equal tempered as a rule.
