If you like the action buy it. It should be like that for a very long time. They are very rugged. I saw a few broken strings mostly bass but never any broken action parts. The hammers appear to be a rubber or plastic core with leather on top. I can't remember how much the whippen assemply is like the grand piano. Yes they always seemed "fast" to me. I tuned them from when they first came out (78?) untill 1988. I was never called to regulate one or repair a broken shank or other parts. I wondered how long the hammers would last. I never voiced one because I was never asked and it never seemed like it needed voiceing. I was never called to regulate one and I never came across one felt like it needed regulation. These were rock-n-roll and pop performance pianos so probably had a stage life of two or three years. I did know some that went on to 5 and 7 years. From the CP series I thought Yamaha might start installing these parts and hammers in their smaller grands but they never did unless they started after 1988. Their tuning seemed to be more stable probably because there are only two strings per note and no soundboard. ---ric ----- Original Message ----- From: Jason Stelzel <epigraf@earthlink.net> To: <pianotech@ptg.org> Sent: Saturday, June 16, 2001 4:55 PM Subject: Yamaha CP80B action | I'm considering a purchase of a Yamaha CP70B or CP80B and I read somewhere | about a reference to one version of it having a "Vienna action" or something | like that.
