Yamaha CS80

Inside the case of the CS60 / CS80 ribbon controller there is the conductive spring contacting the resistive strip when pushed down, am I right?
My question is: I have seen the broken spring splitted in pieces, its diameter being constant (the separated pieces are retracted), while the internal room of the plastic case is reduced at the two ends. I cannot understand how the spring was fitted inside, when it was sound!
The spring diameter cannot be "compressed" and reduced inside its "bed". Or is the splitter spring I see inside not original and too large?
Any info? Is there any picture of a working spring in its place in the right position?
Any help will be appreciated...

I think that the spring gets skewed to be sort of diagonal when it is p ushed down into its hol ding area in the plastic housing, and that is how it fits in the cha nnel that is smaller than its diameter.

Yes, I replaced a broken one a few years ago with one of Kent's
replacement springs. It took me a bit to figure out how it all fit
together, especially since the broken one was so messed up it wasn't
positioned correctly as a guide. Just one of those things that Yamaha,
as a big company with many years experience building musical
instruments, would design so well compared to a little startup that
might have great ideas but not the track record.

To whom it may concern:
I traded with him, he is a gentleman, a kind and prompt communicator, a pleasure to deal with!

Many thanks Fernando.

It was also a pleasure to trade with you sir!
Thanks for your help and maybe we can help each other out in the future!?

Cheers,
TOM

this is correct. i just replaced the broken spring in my CS60 ribbon. In fact, I have been totally refurbishing the unit including fabricating parts for the aftertouch "bar", etc.

My hats off to the Japanese engineers that created this ingenious system.

pic1 - here is one half of the ribbon chamber with spring exposed.

I hope to post a full description of my process complete with pics when completed. I'm about 90% done at present. Thanks to all on this group for contributing much of the info that has helped me.
