KAWAI Forum

Hello,
I have a Kawai K1 rII instrument. Unfortunately, it's broken. Makes very strange noises, does not hold tuning. I found a very similar problem on the internet. the Kawai KTG-001 processor is broken. Are these parts still available?

Dear Mirek,

sorry, but there are no more spare parts available for the K1 series products after more than 25 years.

If the tuning changes strangely, it could also be the xtal circuit that generates the main clock signal. I'd try to change that, too.

sorry for not answering for so long. I noticed that kawai only plays well on sounds that don't use PCM waveforms. If using PCM, the sound from the middle of the keyboard is detuned

I would still check if the oscillator runs stable. This rather sound like a cloking-problem to me. Or bad solderings (cold junctions) on the data-bus. Check the PCB(s) with a magnifier for bad junctions and re-solder them. Works wonders sometimes.
