     Actually I've had this squeaking on very few tokiwa parts but solved th=

plating on japanese pins sometimes fakes off & clogs up felt (German ones to=

   Don't be to hard on the tokiwa parts with a blanket indictment. I've had=20
similar problems with most parts. Contact the importer at Pacific piano.
