Don’t forget that Bob Weigel at sounddoctorin.com still has some stick-on
carbon dots for sale. Not cheap, but a lot less messy than painting conductive
goop on the contacts, and they won’t crumble off.

Thanks. I've been looking at the schem. I assume the key scanning is working correctly. Eg the appegiator would not work. Is it very common for all key contacts to fail? Thanks again
