In this video, I repair a SONY HCD-XG500 Hi-Fi System with a faulty twin cassette deck and a five disc auto changer. The challenge here was to dismantle such a large unit, then find and replace five drive belts on the cassette deck. The autochanger repair was more straightforward, requiring just a push and some lubrication. Apologies for the crackly sound, my wireless mic battery was going but the sound level meter on OBS showed it was still working.
