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 :)

Big thanks for basically secret documents. They might come of help at some point.
