Yamaha CS80

I got one of the ribbon controller springs from RL Music. Does anyone know how the spring is changed or any details which would help?

I've done one. It's a little tricky but obvious once you do it. I
don't have time to write much now but I think I did back then so try
searching the message archive and maybe the photos section.

Thank you for your answer. There is nothing that explains the procedure in the past messages and no photos. I thought that somewhere on the Internet there would be instructions or even a picture but no such luck.

I just wanna let you know that I've been temp. relocated from Germany to Fayetteville, NC (3 years).
Back in Germany I took care of some cs80's and other vintage synth.
The users in this group take awesome care of most issues and problems you can encounter with a cs80 but if you need an on side visit and you are located around the area I'm glad to be of help.

Best Regards
Thorsten

Hi Thorsten,

any thoughts on how to fix a yamaha cs-15 sustain note problem? it sounds
like stuck notes, they just hang.

thanks

I have a couple of springs for spare, could trade one for rare ICs or sell if somebody need it.
The replacement, yes, is a little tricky, not for the faint-hearted but feasible.
I replaced the one in a friend's CS60 very successfully (I am not a professional tech, a medium level analogue fan).
You have to solder the two spring ends to the extreme pieces of metal that fit at the sides of the black case. The case itself can be opened by carefully unscrewing the locking screws.
You have to apply a light tension at the spring, that, having a larger diameter than the available space inside the case, will result with oblique coils.
The operation needs 4 hands at least, two keeping the two pieces of the case together, two maintaining the spring taut in place, two in praying position :-)
Trial and error�

Hi... I can barely remember how I did it. I asked someone who recently did the job (Fernando) to check out your post. Maybe he'll chime in.

Here are some vague steps (reconstructed from one of Fernando's old emails, a phone conversation with Kent Spong, and some fading memories...)

1) desolder three connector wires
2) gently remove the velvet cover - I think you can basically peel it off - go slow and carefully so you don't rip it. it's kind of resistant, but it does come off.
3) partially unscrew the screws in both sides of the plastic case
4) detach the side metal clips on both sides (to which the spring is soldered on both sides)
5) solder in the new spring.... OK, actually, this is the tricky part. You have to take note of how the ends of the old spring are bent and bend the new ones exactly the same.
6) reinstall... I think I superglued the velevt back on... can't remember.

Caveats:

1) my ribbon controller is still messed up. The pitch warbles all over the place. But I think this is a problem with the circuit, not with my repair.
2) I barely remember doing this procedure... but I think most of it is intuitive, apart from the how the heck do I bend this thing correctly step.
3) ... consequently, the steps might be incorrect... though I think they are basically on target.

I hope this helps...

Oh, and if anyone can tell me if they have experienced this warbling ribbon controller issue before (it functions, but the pitch is not steady), please let me know what the issue was...

My ring mod also just started only working on and off, so I think there is probably some deep rooted problem in the synth :(

best - Damon

Thank you for taking the time to reply. This is good info. I might photograph the procedure since the info is not out there.

I completely second this, Damon.
The procedure is the same as the one I applied successfully.
I add some more caveats:
1) You'll need help, at least 6 hands in total: two for keeping the plastic case slightly open while other two hands position the metal clips, applying a certain tension to the spring. The other two hands? in praying position :-)
2) Due to the spring larger diameter than the inner room of the case, the coils will be (at least in my machine) angled, they'll look oblique through the case slot.
3) One more suggestion: you have to glue the velvet very taut if you eventually want to press the whole into place in the correct position; if not, it will not reach the final settling and you will have to unglue / break the delicate velvet and redo the procedure
4) Be careful not to overheat the terminal on the case when soldering the wires. The case would melt and that is the rarest part of the ribbon controller...
The CS60 which I worked on exhibits a perfect function, after this.
Hope this helps
Good luck!

Fernando

Can I buy one?
