Humidity and New Parts

[Farrell]

"> A low powered rod (maybe a 15 watt 36" would be safe under the keybed)
connected to the humidistat under the piano....." I would recommend trying
to place the humidistat controlling this rod inside the keybed area. There
may be room up against the belly bar in the hi-treble section (where there
are no dampers). This will ensure that the humidistat is reacting to the
action environment, rather that the environment under the keybed, where it
could be quite a bit cooler that inside the action cavity.
