Hi all, Just bought my first set of decks in the form of a set of Technics 1210 mk2's. I bought them from ebay and the overall condition etc is mint but on one deck, the tone arm appears to nose dive towards the deck alot more than the other. I have al the weight/height settings matched on each deck but one dives down whilst the other is level. Its extremely difficult to tell but the only thing i can think of is that the tone arm is bent. When playing a vinyl, it gets about half way through and then skips back and forth on the spot and doesnt carry on and does this on different records. Just wondered if anyone was able to shed any light on this at all and at the same time, give me some advice on how the weights/height of tone arm etc should be set up. I am slightly dis-fortunate I think in that it appears the dial that tells the weight setting seems to be spinning freely and so isnt reading the true weight. Any help much appreciated here guys.
