I've got a SL-1800 (1200 series predecessor) which has got a 25 yr old cartridge on it. It's louder on one channel than the other. Before I go and buy a new cartridge I wondered if there's anyone local I could borrow a headshell + cart off to try, or I could bring the deck round and try it at yours, so I can tell if that is the prob.

Just trying to cross off all the variables...
