Congratulations on your freebie. You will be pleasantly surprised how good it sounds when you get it going!
The speaker cables are 2-pin DIN male at one end female at the other (assuing you have a set of B&O speakers), you can use the 5 pin DIN Tape in connector at the front to connect a CD Player, you can buy suitable RCA to DIN converter leads on eBay or from Maplin relatively inexpensively, so there is no real need to make your own leads.
