Sharp- RT-1120(BK) 1 Owner Stereo Dual Cassette Deck NO MANUAL - Looks Great! I Tested Without a Receiver (Worked Great at Last Use) as Best I Could. Powers on and One Deck responded to all Buttons Pushed. The Other Deck Buttons did not Respond Well and Were Difficult to Push. Maybe a Great Buy if you're Interested in This Vintage Treasure. Better Hurry, Thanks.
