I work with Petrofs daily. They are really "big" here in western Norway.
This I believe is mainly due to the fact that they have a relatively
nice round basic sound. There are at least three big problems with
Petrofs.

1.  The action. I dont believe Renner assembles it, and I question
whether all parts are truly Renner. In any case You must expect to have
to go through the entire action checking everything from basic geometry
to allignment of whippens, hammers etc. etc. ad absurdum before you try
and regulate the action. Otherwise you can expect a regulation that will
be unstable and uneven.

2. The tunning block is often of poor quality and fitting to the plate
leaves much to be desired. On more then one occasion I have been able to
insert a tuning mute between the plate and the block so that it goes
over an inch in. Amazzzing. Petrofs are famous over here for not holding
tunings. A guy I know in Seattle automatically sets a Petrof grand out
of the box on its side and starts pumping in epoxy to fill the gaps.

3. Bridge pin work is also very bad. Makes for a lot of false beats.

My advice is buy a Samick. Still, if you must have a Petrof, and are
willing to take care of the action problems and make sure the tunning
block is reasonably well adjusted to the plate, you can live with the
false beats, and like I said, they do have an ok sound. You can stand a
few feet from a Petrof and hear it played and actually be a bit
impressed. If Petrof combined japanese precision with what they already
do right it probably would be en excellent piano. Unfortunatly they
dont.
