Sound tower not working - repurpose with Raspberry Pi?

My soundtower quit working. It powers on but no sound from an ipod or from component audio cables in the back.  Are the speakers themselves repurposable perhaps by removing the electronic boards and replacing with a Raspberry Pi?  If not, it's going to the dump.

Just get a cheap audio amplifier with the connections you need and put in there - that is if you can do without the display stuff...
