Thanks! Ignore my PM, I thought you'd sent me a link I couldn't see.

I have them now. :)

A night or two ago I have:

- Changed fuse and moved wire jumpers to the 240V setting, and tested ok, so it works without the step down transformer now (was 120VAC),added 240V 125mA SLOW BLOW printed label to the back of the keyboard
- Fixed the main encoder which had the PCB flapping about inside, bent the metal inside nicely, cleaned it, reassembled tested and then melted the four black plastic posts a little so it stays shut - main encoder works perfectly now.
- Found snapped off clear plastic lens from Slot 3 LED inside, glued back into place.
- After using all suspect buttons frequently, they all work fine. I suspect contacts inside had oxidised. Not so much worn I don't think, since they all work perfectly now.

Really enjoying it, will have a good look over the schematic now :)

Mr. Marko. I'm from São Paulo, Brazil and around here I have 7 Clavia equipment for repair and I can't get the diagrams at all! I've already tried to contact Clavia and they don't answer us. There is no authorized service here either.
Would it be possible to help me with the schemes of stage 2 ex, stage 3, and stage 4? Or at least some of them.Thank you very much in advance! 🙏🏼 my email is chelrebeca@gmail.com

Looking at the page https://www.nordkeyboards.com/distributors/ the official Clavia/Nord distributor for Brazil is in San Paolo actually, you should contact them.

There is currently no distributor or authorized service in the country. I'm from São Paulo and I have a technical assistance specialized in keyboards. I can tell you that it doesn't exist in Brazil. I'll wait for an answer from Mr. Marko.

Thank you for trying to help 🫱🏼‍🫲🏻
