I have a nutone intercom/radio system in my house than no longer works. The transformer got fried by lightening, and when I tried to replace the transformer, it still didn't work. Nutone systems are very expensive to replace. What I would like to do is to connect a cheap home theater system to the existing speakers, so that I can play mp3 formatted music cds. There are 3 existing speakers, and they are 25 amp 6 watt speakers. Does anyone know if this is feasible.
