Can you use a McIntosh C12000ST preamp with a McIntosh C500 controller?

My goal is to become the proud owner of a McIntosh C12000 dual cabinet preamp/controller which I intend to use with my McIntosh MC1502 amp.  However, because I can not swing the $16,000 cost of purchasing them new, I went ahead and paid $4,000 for a used McIntosh C12000ST (preamp) unit hoping that some day I would be able to pick up a used McIntosh C12000C (controller) unit at a similar discount.  Although the search is now in its 7th month and I have yet to find anyone selling just the controller module for the C12000, I recently came across a McIntosh C500 controller for sale.  So, the question is....can one use a McIntosh C12000ST preamp module with a McIntosh C500 controller module?
