There were two models, the CP70 & the CP70B. the difference was the scaling and the 'B' had the transformer as part of the power cord. These instruments should always be tuned with an amp, as the pick-ups hear a different harmonic. I tuned the first one in Australia and had been looking after many CP70Bs and CP80s until the digital pianos took over. They can be tuned successfully by ear, however the octaves must be expanded quite a lot. They are known to break the covered strings on a regular basis, and I stocked many replacement strings for such pianos. Best of luck.

I've never seen one of these things. I'll have an hour and a half, and it's supposed to be a "clean up" tuning. Can anyone give me any info on these things? les bartlett houston -------------- next part -------------- An HTML attachment was scrubbed...
