Yamaha CS80

All right, my CS-80 now runs (I used a ready-made autotransformer - didn't 
build anything myself).

It's remarkably well in tune, considering the voyage around the world, but 
of course I still have to tune it to really enjoy it.

Apparently it's not just the M boards that need tuning, though.

So, stupid question: How do I get to the boards below the keybed?
I see the two screws on the bottom, fine.
But do I have to remove the left and right end blocks before I can lift the 
keybed?

And do I have to put the card cage down to normal position, or can it stay 
up in service position, for lifting the keybed?

Yikes - I do this in my sleep, so it's hard to actually remember the steps!

You have to remove the side panels (glide/sustain on left, power switch 
on right). There are screws from the bottom of the case and machine 
screws from the top of the panels.  The ones from the bottom are a pain 
to line up to put it back together when you are done.

There's also some big screws on either side of the keybed frame.  I 
think there are two big Philips-head machine screws and one flat-head 
wood screw on each side.

You want it in the up position.

Good luck!

I think you have to remove the 2 side pieces to access the lower boards.

a youtube video tutorial of a CS80 being tuned would be great.

anyone have a CS80 AND a Video Camera?

i do have a camera, and an 80, but i will not be tuning mine for a bit! i did write up some tuning tips that i wished were in the manual/service. consider this only a SUPPLEMENT to old crow's site and the manual, the two BEST sources for tuning. hope this helps you.....fyi, you should read the whole thing before starting...

I know this one, from Oldcrow's site:
http://www.cs80.com/docs/adjustment/
I've sucessfully tunded my CS-50 with this, including the octave / semitone 
stuff.
But even though the CS-80 is similar, I have deep respect of that beast 
before I begin. I just brought the keybed / wooden frame into the up 
position, and it really feels like working on a *car*, not a synth.

Where can I find your tuning tips / supplement?

JH.

a pdf with the tuning tips should have been attached to the message(email). let me know if you dont have it in it.
