[pianotech] Loose Coils

[Will Truitt]

Hi Jon:

How is this beast to tune, what with the tuning pins bearing against the
side of the hole at the front?

A long time ago, someone effected a quick repair on a M&H AA.
A string broke in the treble and the coil was unwound slightly to get two
coils on each pin.

The left wire on the upper unison stays in equally good tune as the right
wire on the lower unison.

I don't neaten it up when I see it because I'm tuning for a performance and
I don't want to introduce an unstable unison due to 'coil creep' just before
use. I never remember to tighten it up when I'm in the building other times
but there is never a problem with stability on the loose coil; if anything
it's usually better than its neighbors.

If it ain't broke, don't fix it.
