I have some gemini xl 500 and some weird carts. but for some reason when i play tunes like alibi - eternity or members of mayday- 10 in 1...the needles would shake so bad. Its probaly happening because of the cartridge playing the record and it causes it to shake the needle? is it my cart or my tonearm weight? thanks

If the tonearm only starts to shake when you play certain records, I think it'll have to be because of the way the record grooves were pressed. I don't think it's your carts..
