Out of interest why do you need new feet? I'd strongly recommend buying something like these instead, reasonably priced and made a great difference on my old CD63 as they will on your KI.
I recently purchased a replacement Bass/Treble Knob for my Marantz amp from the UK supplier Charles Hyde & Son Ltd. You can ring them on 08709 909474. Took a few weeks to get as they don't hold everything in stock but a good service.
