Kawai makes fine pianos in their Japanese factory, this is no exception. This piano was not made in polyester. The older ones do not have the perfection of polyester. But the design of the sound and action is superior to current equivalent models.
This Kawai has 2 pedals, a practice pedal is now a current feature we can retrofit as a lever on the side of the piano.
It is very similar to a Yamaha U1D of its age. One of the defining points between old and new is wood vs metal. The action of this older K8 Kawai is made of wood, the U1A newer model action parts are mounted on aluminum. Wood is easier to work with.
The metallic mounts are less likely to warp but the screw threads are more in danger of breaking beyond repair. It is, therefore, better for the longevity of restoration to have wood not aluminum, it shows the manufacturers are aiming to enhance any future restoration. The economy of using wood seems like a financial decision rather than an improvement. The only downside is that metal is more prone to becoming noisy.
The Kawai K8 is older and has not been regulated, much regulation is needed. These older Japanese pianos tend to sound more mellow that modern pianos from the same line. We very much like the older Kawai and Yamaha uprights. The sound is very rich sounding to play. A pleasant tone encourages more play generally than a brighter more modern tone.
Other work needed: cleaning of keys, pitch-raise (hear 3:50), about 8.5 beats flat. A flat piano will sound less lively than a piano at A440.
