Phoenix Engineering Roadrunner

I have lost the magnetic piece that attaches to the platter. Does anyone know of a replacement? Or where I might find one?

 I could not find the email address of the company founder. 

Thank you.

Looks like SOTA is going to be taking over production. Perhaps you can call them to see if they can help you.
The tiny magnet that attaches to the bottom of the platter is being sold on ebay by a Phoenix Engineering dealer who has some left.
Otherwise any similar size and shape magnet would probably do.
