Vintage hi-fi system (Arnside LA5)

Vintage hi-fi system, which comprises stereo amplifier, stereo tape deck, 3-band tuner and all the associated power and audio cables. Speakers 38cm high, by 22cm wide, by 21cm deep. Speakers and amplifier work. Tape mechanism and tuner both power on, but suspect possible perished band drive, because tape mechanism does not turn and tuner adjustment knob is ineffective.
