I had to replace two of those that got bunged, plus the dual AF/SUB pot, a drop to the face of the K3. While it was straightforward, it is a good bit of work, and it's careful soldering. The same thing would apply if your encoders quit working due to wear or ... I wouldn't take it on unless you lose operation.
Mine have always had a bit of play. I've gotten used to it and don't think about it any more. Every now and then a slow knob turn on one of the encoders doesn't move the setting, but I think that's an internal time out thing waiting for the other half of the state change to come across the line into the CPU. Don't expect people to be creeping with the adjustment. On Thu, Dec 18, 2014 at 10:32 PM, David Cole <[email protected]> wrote: > > Hi, > > I have a new K3, well, maybe 4 months old now...
