1980s Onkyo Turn Table

Can I still buy a new needle for something this old?  Is it even worth it?  It was medium priced back then.
More than likely you can buy a new needle. Does the phone cartridge mounted on your turntable's tonearm have a removable stylus? If so, you just need to know the make/model of your cartridge and order a replacement stylus. Lots of sources for replacement stylus. www.needledoctor.com is just one, of many, sources.......
Get the new Grado Black Prestige cartridge! $79 - or so from Needle Doctor! It will sound a lot better than that cheap Audio Technica or whatever is on the tonearm now!
