Build a compact disk player

Building arecord player, cassette or tape recorder, or compact-disk player, is often hampered by the mechanical construction and the availability of certain parts, particularly the deck. In the past, manufacturers have generally tended to be reluctant to make tape or CD decks available to the retail trade, but Philips has recently decided to break away from this policy. A kit, containing its CDM-4 deck and associated (populated) mother board, can now be obtained from certain retailers at an affordable price.
