My local analogue tech, who owns a CS80 himself, says that the
aftertouch sensors on the CS80 will deteriorate over time and need
replacement. He thinks that Yamaha threw away all the old parts stock
for older keyboards, such as these CS80 sensors. I think he mentioned
they were a pyramid shaped rubber sensor underneath the keys.

Has anyone heard of, or experienced, this degradation in the CS80
aftertouch sensors?

Does anyone know of a source for original or replacement CS80
aftertouch sensors?

Is there anything that could be used as a replacement, or could
replacements be made somehow?

Does anyone have information on how these sensors are
constructed...materials used, shape, assembly, etc.?
