Service/repair Manual required for Philips AS305 (Midi Hifi)

Hi I would really appreciate it if anyone could assist with providing service/repair manual/schematics for a Philips Midi Hifi ( AS305 ) that was made in 1991. The tuner is very weak on MW and has no station/radio on FM, except some soft audible static. ( FM aerial is connected when tuning). Casette player rubber gears have disintegrated with age. CD input and phono works. Any advice faulting the FM tuner would be welcome. Thank You. Dog2.
