Hey guys, so here I got a Phillips MCM720 Micro system and the problem is that the tower (receiver) had gone full retard and doesn't work anymore. However, the speakers (2 way bass reflex) work perfectly fine, I just got those red and black vires without a possibility to use them. Is there any way to make them play again? Without a receiver? Or perhaps using something much smaller which could be compatible a play music from my phone, SD card? I don't have any CD's anymore so it would be no use to buy a new original receiver. Thanks for the answers.
