Your BS9000 is a Mk2. I need the serial number to determine it's exact age. Serial number can be found under the keypad.
Any version of powerlink cables will suit the BS9000/BL8000 combination.
A flat bladed screwdriver will do for adjusting the sprung suspension. You do not need a special tool. The arrows on the screwhead should point vertical when the Beocenter is mounted.
The CD mechanism should be replaced to overcome the random pause problem.
