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.
