#2508648 - Today at 04:52 AM Kawai Ca 63 buzzing noise

Hi, i have this perfect condition used ca63 since a couple of months, and it is just oh so lovely. There's just one problem: i keep on max volume ( big room ) and, depending on the weather ( temperature ) it produces a buzz, resonating with the notes' frequencies.

It apparently comes from the keybed area. If i turn down bass, or volume, or both, it gets a bit better ( result apparently vary according to ambient temperature).

I tried and grabbed some cabinet areas while playing and hearing the buzz: the plank in front of the keybed, where the red led is located, the fallboard, the music stand. Turns out by grabbing the plank very tight, the resonance calms a tiny bit, but there's nothing really lose, since i'm not really able to stop the buzz by just touching here or there: it rather looks like coming from deeper within, and then building up thru different components.

It is not that serious, but I wonder if i can get rid of this. Any clue?

Bellicapelli, it may be worth contacting a Kawai dealer in your area, and/or Kawai's Italian distributor Furcht pianoforti to seek assistance. Even though I gather that you purchased your CA63 second hand, the dealer/distributor may still be willing to arrange for a technician to visit your home, and attempt to resolve the matter for a fee.

Kind regards,
James
