And to be clear, the contact assembly I ordered is new-old-stock, not
used. Your email here is the only description I've seen on "how to"
repair the contact assembly. I think this is a ripe topic for a how-to
with pictures. If I can make successful adjustments to my assembly,
perhaps I'll document it on DW8000.com.

I have managed to fix a keyboard even after a heavy impact due to the synth's falling from my car's roof (while car was standing...).

I am sure there are some key left with flawless contacts that may serve as a template. There is a "note on" contact and there is a "note off" contact. The latter being more prone to failure due to oxidation and wear. It is important to have all contact strips in the same position, else the velocity will not be sensed correct. I never had a used DW8000 keyboard where the contact postiion was the same for all key - with negative impact on the velocity. So even if note on and off is sensed correctly it might be worth adjusting the contact strips after all these years of use.

You need to use a strong oxidation remover (in Europe e.g. Kontakt 60), but ,in any event, you need to remove the applied antioxidant after use (i.e. once contact has been re-established) by means of some neutral solvent (alcohol or de-greaser will do; in Europe e.g. Kontakt 61, Kontakt WL or Tuner 600)
