Okay dudes and dudettes, you gotta help me out! I just got this new record player for free, its pretty old but it's in mint condition and seems to function alright and stuff. The problem is, I tried it out for the first time today and while noise was coming through, it was very low and there was this high pitched screeching sorta noise over the music. Does anyone know whats wrong with my turntable or if its something else? I plugged it into an amp that does 5.1 DD and all the new stuff, maybe its too new for it?? Oh and the turntable is a Realistic Lab-400, oldskool :P Any ideas on what may be wrong and how to amend the situation would be appreciated :D |

have you earthed it to something like a radiator? also, check your amp have a phono stage/pre amp ('im guessing both of these are the problem) you can get pre amp from most hifi stores.. |

if youve plugged it into line in, then it wont work. plug in phono socket or get a phono preamp or dj mixer. id imagine the cables from the deck are rca phono leads, there should be 2, one red one white generally. red=right channel. there should also be a earth wire which you attach to the grounding socket (usually a screw terminal) on the rear of the amp/mixer/preamp... or onto a radiator or sink or spike in the garden. don't put it on the painted(insulated)bit of the radiator. try wrapping the phono cables in aluminium foil and grounding one end of it, to reduce ground hum(which is high in phono cables since they are unbalanced). make sure the foil doesnt touch the metal contacts on the phono cables. use a multimeter to check the cables. (should have very low resistance unless there is a problem). perhaps you need a new needle or get a new better cartridge if the deck has a headshell to mount it on. also check if the mains socket has a third ground cable, test that as well. perhaps avoid using it near any mobile phones, tv sets, microwave ovens/transmitters, wires carrying signals e.g. timecode. finally check that the high pitched sound is not part of the recording on the record :) thats all i can think of, hope it helps. |

as it happens being be a bit of hifi enthusiast, i have a couple of phono stages for sale (will allow you to use a turntable with an amp that doesn't have a phono input). one is made by QED and cost me £25. for sale for £10 the other is made by NAD and cost £30. for sale for £15 i have recently bought a new one made by pro-ject |

sounds like good value for money, if anyone doesn't have a phono stage, these are cheap and by good brands. |
