Steinway underlever spring tension

[Jon Page]

Lance,
It is well worth the effort to replace the back action as well.
The spring-loaded sostenuto tabs make all the difference in the world.
I would say that it is as important as replacing wippens.

With the Renner USA Underlever Kit is very easy to make a duplicate rail.

In the back of the instruction booklet which accompanies the kit is
a list of suggested tensions.

Regards,

Jon Page
