Well by hook or crook it looks like the Poly is now fixed. Famous last words, I know, I've probably cursed it now!
I tracked the problem down to being IC17 (mainly through luck). It is a 40H074 and looks like it is part of the master oscillator. It fixed the tuning problems and the issues with the joystick.
Thanks for all the input on this one and putting up with my often stupid questions. I must admit, after repairing a few synths I have found the Poly 800 to be quite a tricky one.
Cheers
