After a big sortout of our loft the other day( 250 square meters). I found a Garrard turntable gt 35p and about 200 lps all 1970s stuff .We think the previous owner forgot them but he is dead and his wife claims their not hers. Any way I have tried to set it up to my Arcam a90 which has a phono stage and the quality of playback is mediocre and there is some significant humming even though I earthed it. I think it probably needs a new cartridge and the tonarm looks a bit too lightweight to be any good but I am keen to restore the turntable as it seems a shame to throw it. Does anyone know how I do this as I am totally lost. Can i buy any cartridge and tonarm for it or are there other things I need to know. i am a total novice when it comes to vinyl. How do i stop the humming is this down to the cartridge and tonarm or something else???? Thanks for any help.
