    Sorry for the silence everyone. My engineering rellie has gone on holiday so the quest to discover the cause of the knock...knock...knock... has been put on hold until early September, whereupon we will both be applying ourselves to it more fully. If we can't discover an answer I'll film it and put it on Youtube for everyone's amusement. For all I know, this may be a fault that it has always had to some extent but which has only recently got bad enough to become audibly apparent. But I doubt it.

    Anyway, thank you to everyone who has read this and especially those who have posted. I'll be back with more once I know more.

    Thank you

    All you need to do is clean your hands of grease/sweat, remove the platter and start the drive. Carefully and gently touch the driving side of the idler while it's rotating and see if you can "feel" a bump or rough spot. Crude, but it worked for me
