Hello. I accidentally found your response via another Internet search! THANK YOU for your reply. I was beginning to believe this, but had no proof. So the SK200 is a typical keybed of the time. I am so relieved to know this. I could have taken piano lessons (again, haven't played since childhood, and want to), for the amount of time I have spent trying to fix this sampler. It has deep sentimental value - my mother played beautifully and had a catastrophic heart attack. My father bought this for her in hopes that bringing her a keyboard might 'snap' her out of her mental state and wake her up. Alas, she had lost too much oxygen. But I need to fix this unit and have it for my future grandchildren when I go. THANK YOU!Hello. I accidentally found your response via another Internet search! THANK YOU for your reply.
