Krell KPS 20i/l 5 Point Magnetic Clamp Puck

I have a Krell KPS 20 i/l That I just recently picked up but I have no way of testing it becasue it does not have the 5 Point Magnetic Clamp. Does anyone have one for sale or know where I could get one. Krell is looking for me but it does not look promising.

Any help would be appreciated.
