If you are prepared to tune by ear you could very well end up less than say the recommended 1.5gms.The manufacturer's spec is really a guide only but I don't think you would end up as low as 1gm.However go to Loyd Walker's site and look at the FAQ about tuning your turntable to learn about this it,is really required reading.Here is a link http://www.walkeraudio.com/fine_tuning_your_turntable.htm
