Good suggestions so far and I would like to add removing the natural curve 
of the wire at the
v-bar and front duplex.

I have a lever I fashioned out of a length of wood (scrap pin block) and 
a  spinet caster.
I place a block on the keybed as a fulcrum for the 'string leveler' and 
press the wire
upwards, first on the duplex side and then on the speaking length. With a 
dowel and
hammer I coax the wire around the front duplex.

This may not get rid of all the false beats but it surely cleans up the unison.
