I have a Technics Digital SX-PR903C that needs some key tops replaced. Does someone have key tops for sale? I also need instruction and advice on how to replace them?

The keys needed are 2-F, 2-G, 2-A, B, 2-C, D, E.

Thank you

Well, I can help with the ADVICE part.

Take it to your local piano dealer and let them do it.

As I understand. Korg is using the Technics keybed. Same one on the SP250. You might talk to Korg service?

Are you sure about that? I really doubt it. The Technics is a much older generation of instrument, made by a totally different manufacturer. Korg SP250 uses the RH3 action which appeared a long time after Technics disappeared as a company. In fact, I can't see how there could be any connection between these two models.

I found the link to place order for parts:

I also replaced the 3.5 floppy drive with a GoTek USB floppy emulator. It works very well but the floppy controller in the piano is slow. I use a 4G memory stick and the GoTek sees it as 100 floppy disks which are addressable. Cost 27.95 on eBay.

Repairing the keys I am using several approaches. I have first used an acrylic plastic polish. This has smoothed much of the damage and now playing the piano the damage is hardly noticeable.

Next I plan to use an acrylic repair kit. This is clear material that can fill pits and cracks etc.

Lastly then move some keys and also order replacements for a few of the severe keys. I did find a service manual for 5.00 on the Internet and it explains in detail how to replace keys.

So far I am pleased at the capability of this DP even tho it is 10 years old. It has features that many of the newer ones still don't have.
