Further to my earlier post, thanks for the replies, will try the factory
reset. I presume this is the one detailed on p100 of the manual. Will let
you know if it helps. Further to Jerry's comments, the distortion does seem
to be related to the main volume setting and is reduced if this is set at
around 70-75%.
Thanks again
