Hello! I was wondering if someone could help me? I just picked up Technics SL-d3 TT with a Audio Technica AT 15Sa cartridge and AT 15ss needle . The needle is shot what would I replace it with and how good is that cartridge and how old? I dont wont to spend to much,but I do want something descent! RT now Im useing a ADC OLM 30 mk111 . I had it in my collection it was never opened from 1975,but it is a spherical!
