kawai dampers

[Fenton Murray]

Re: kawai dampersSpring tension should be address here, not weight, IMO. Lift up on several underlevers with a gram gauge to determine spring tension. Kawai's do have an efficient damper system, but the felt will certainly become hard, contaminated, vertigried, what ever under the right conditions, like our costal climate to name one. Also, I have noticed friction problems in many older Kawai underlevers, either in the block or the flange. If the damper wire is not coming straight down, it can bind the assembly. Guide rail bushing?

    Wim's idea of weight is well worth looking into...what is the damper weight suppose to be on a Kawai?   Don M. should have an idea...

    Kawai's are  pretty well made and not likely the damper felt unless damaged or hard...

    Not yet, but I can't ever remember having a problem with Yamaha dampers.

      I really like Yamaha felt.  Easy to work with and efficient. Have you used it?

      Hello fellow damper lovers, 
        
      I've got a Kawai kg2-d mid 80's with the usual bass damper tone leakage. Under lever pinning is fine, guide rail not binding, strings level, and no amount of wire bending is seating this damper enough to stop the tone leakage. 
      I'm going to replace the felt and see how that goes, what would be the best felt choice as well as any other suggestions? 
      Thanks,
