Yamaha CS80

I don't believe the plane of transportation has any effect. It 
doesn't matter in what plane the vibration comes in. It's just 
vibration itself in combination with the spring-force that's left 
inside the trimmers (the older, the less strong the trimmer-shaft 
makes contact).
If the casters were on another side, it would result in the same 
risks. Just carry the CS80 with two persons if the floor is uneven.

I feel the older the synth gets, the more problems these trimmers 
cause (too less spring-force, dead spots). Most of the problems I 
had were caused by these trimmers (vca- adjustments for instance) 
Are these trimmers, or good new 1:1 replacements, still available, 
does anybody know ?
