Ive had my decks for about 2 years now, not sure how long the lad before me had em though. Just startin to come across my first problem with them. Up untill about a month ago they felt great and i could always manage to just thrown the first beat of the tune straight in without any problems but now my decks are sticking (sometimes they work, sometimes they dont). Even when I'm just holding a record in cue the platter doesnt even turn around and it feels really stiff. Does anyone have any idea what it could be?

Also Ive had Ortofon Concordes sonce i got my decks and have used em about an hour a day for the last 2 years, how often are ya supposed to change em?

Cheers if anyone can help
