Hi All,

since there seems to come back some life into the group, I was always wondering about one thing: Before I had a CS80 I was always reading about what a headache the machine is regarding staying in tune over time. Some technician even told me once that just by moving it around in the room detuned some oscillators.

I haven't made that experience. Actually I calibrated mine from ground up, which was quite a ride that will cost me a few years of my lifespan, but I learned a lot. I documented it, mainly for myself if I have to ever do it again :) , in case of interest : Anyway, I calibrated mine in 2016, meanwhile I also moved to another apartment. I recently checked how good it is in tune and it is slightly detuned here and there, but it is not bad and I cannot really hear it when playing.
I wonder about my fellow CS80 owners what experience they make or made regarding this.?

Michael
