I've just bought one of these on ebay for 40 quid. It looks in decent nick (from the photos anyway), and hopefully it will give me good playback of my old vinyl (currently gathering dust in attic). How good were these decks? Is there anything i should do to improve sound, bare in mind the deck is from 1973! I've bought a new belt but am a bit unsure of what modern cartridges would be compatable with this deck, also should i be thinking of servicing eg oiling of bearings. Thanks in advance.
