Kurzweil Mark 5 Ensemble Grand. Used many years ago and is kept in very good condition - just the amplifier is not working . I was told that there is inside the system a battery which needs charging or replacing and that could be the problem but I haven’t done anything as I don’t have time for it ..There is noise coming out when I plug in but no sound is coming out ..Could be a small fix and up and running It comes as one unit and needs 2 people to lift it as heavy
