I have recently purchased an SL-230 Technics, i had bought it to replace an older model my parents own but didnt work. can some one either help me out on the calibration cause i have all the wiring correct, but im getting a hum and little to no movement. This is a birthday present and i would love for it to work so if anyone can help out that would be awesome. Also if anyone knows were i can get the instruction booklet for free online, or if worese comes to worse somewhere i can buy it
