I just got a second hand Kurzweil SP76. The problem is that if you play open chords with sustain pedal pushed on, the sounds immediately gets distorted. If you leave the keyboard switched on for a while, than it will play a distorted sound even with no sustain on. Any idea what the problem can be, and if it's worth fixing ? Thanks
You do have the sustain pedal plugged into the "Switch" jack and not the "Control" jack, right? It's easy to confuse 'em...

I used a higher current power supply (12v 3.5A) and the problem does not show so far, it even sounds better now. Does it still have a problem or has the original PS gone bad ? The original provides exactly what the keyboard needs (0.5A) (Gil) wrote in message news:<>... > I just got a second hand Kurzweil SP76.

I connect it to the "switch"... should I connect to the "control" ??
