This will probably be to do with the tonearm and cartridge compatibility. Do a google search for "tonearm cartridge Resonance" and you'll find a few links explaining the phenomenon. Here's one of them I found http://www.gcaudio.com/Archives/tonearmcartidge.htm
Putting more playing weight on will help the cartridge to track but will make the sound become more 'dead' and will wear records quicker. However, what wears records out the most are mistracks. I don't know too much about Dj turntables and the like but I have heard from very many sources that the arms Technics come with are not really very good. Origin live (www.originlive.com) make nice cheapish arms including one which they now aim for the DJ market. I have a OL modified rega arm on my turntable and it's superb but I've no idea what it's like for scratching etc. Please remember to look after your Vinyl as it's a very precious and you owe it future generations who may want to hear this music. ----- Original Message ----- From: <[EMAIL PROTECTED]> To: "scotto" <[EMAIL PROTECTED]> Cc: <313@hyperreal.org> Sent: Wednesday, March 05, 2003 8:56 AM Subject: Re: (313) tone arm wiggling > > I also noticed with that table when I cue records or try to scratch the > needle and tone arm move around a lot and usually pop out of the groove. > the > other table does not do this. > > I've been experiencing this problem a lot recently.
