The headphones socket is in the command that opens when you push the dedicated side of the front panel. There you can also start a radio to see if it sounds. I suspect you didn't read the manual since you can't find the headphone socket: you should find it (available here in Beoworld for silver and gold members) and read it carefully. Those units are old and sometimes have a different handling than moderns sound devices.
There is no dedicated mini jack entrance to connect your phone (again, its an old device from a time phones were not media players). You must use a mini jack to twin RCA wire and connect it to the Tape 2 ou CD input.
So far it is complicated to tell if your problem comes from the amp or from the deck.
Also know that BM5000 is a wonderful piece of hardware (even more with the rights speakers), but nowadays they are often faulty.
