I am bringing my old Dual CS-721 (vintage 1976) out of retirement. I had some work done on it around 2002 and it works great. The cartridge on the other hand needs some help. It currently has an old Ortofon LM30 cartridge. A replacement stylus costs about the same as a new cartridge of comparable quality. Therefore, I am looking at alternative cartridges for this table. Any recommendations would be greatly appreciated, especially from those using older direct drive turntables
