Remarks[edit]
No longer available - Widely widened pickup from the mid 90s. Purchased from several manufacturers and installed under their own labels, Was also listed under different names with different needle colors by Audio Technica: AT 90, AT 91, AT 2001, AT 2002, AT 2003, AT 2004, AT 2005, AT 2006, AT 3000, AT 3600, AT 3600 C, AT 3600 L, AT 3601, AT 3650, AT 3650 C, AT 3650 L, AT 3651, AT 3652, Sanyo MG 40, Yamaha CG 7700,CG 7800,CG 7900 - Denon DN 82, Dual DN 239, DN 235, Sony, Kenwood.
There are also needle shapes available for this system with an elliptical cut (AT91E) but they are very rare. They appear among other things on Ebay under the designation "ATN 3652E" as a reproduction needle. In addition, Thakker offers a replacement elliptical needle as "Thakker Epo E".
