Humidity and New Parts

[Mark Bolsius]

G'day Karin,

We have problem sin various parts of Australia that are similar...and I'm
the Renner distributor here. (here ends the disclaimer)

My advice is to go with either Renner or Steinway components.
When you get the parts, let them sit out of their packaging for a week or
two or three, then repin them that way the changes that will happen have
occured and when you repin it should be reasonably stable.

I know it's time consuming, but it will solve your problem.

If you install a Dampp-Chaser system, you'll have some changes, but once
they've occurred things will be stable...I wouldn't worry about the loose
tuning pins, because they are  the least affected by the system. A low
powered rod (maybe a 15 watt 36" would be safe under the keybed) connected
to the humidistat under the piano won't cause any trouble, but it will keep
the action stable.

I'll be interested in other points of view....
