Does anyone have a schematic for the Nutone IK-25 door intercom. The product is not sold by Nutone anymore, however, there are millions of them in existence. And, they are still being sold by many companies that have existing stock. Nutone told me that they don't even have a schematic. I'm not sure I believe that, but they did say they purchase the unit as-is. I'd like to make a few changes in the way it operates. I'd like the indoor station to indoor station to be non- private, just like it is to the door station. Any ideas?
