The Audio Technica ATN5V is a modern slender .6mil conical stylus that can serve as an entry level downgrade replacement needle for the Signet TKN7LCa, TKN3Ea and the TKN5Ea styli as found in the TK7LCa, TK3Ea and TK5Ea cartridges etc. Alternately, any "212" below will also fit/work but without a stylus guard.
