This is a genuine Acutex USA International "Standard-series" M210IIE or 210 II E replacement stylus for 16, 33 & 45rpm, not for 78rpm. This ORANGE .3 x .7 elliptical needle looks similar but is NOT the same as found in the(LPM style) 310 III E but it can be used in the 206 II & 207 II E cartridges as an upgrade. This allows a nice fidelity upgrade without the hassle of having to replace the entire cartridge. In 1980 This cartridge retailed for $80 USD. As of 2009 multiply that by about 250% for a current retail value. The entire Acutex line is completely out of production so all items are N.O.S. (new old stock) but are in perfect original condition because our supply has been stored under gentle conditions.
CAUTION!! Acutex made 2
completely different cartridge body styles and did NOT change the model
numbers!! This needle is for the "LPM" cartridge body style. Be
careful not to confuse it with "M" style needles
which look like this --> .
NOTE: 2009: 8 years of research is now complete on this fantastic rare line of products! We have the most extensive line of Acutex needles available on the web. Almost everyone will try to sell you the universal part number "733-D7
" which will be a master disaster since it won't fit into your Acutex cartridge. However, we now have 4 of the original 6 of their most popular "LPM" series models available in stock in the original factory packaging. All information derived from the rare 1980 Acutex Cartridge catalog
and augmented in conjunction with modern day customer feedback.

All the [300 & 400 series]Acutex pickups used a propriety variant of the MM system the company called "Tri-Induced Magnet System", see brochure for details regarding the difference,between this system and a normal MM cartridge. The company claimed the best channel separation in the business. The range started with the M110E that featured a simple "line contact" stylus (actually a elliptical variant), slightly more expensive was the M210 IIE and the M310 IIE, those 2 had an elliptical stylus .3x.7. The updated M310 IIE has an improved frequency response of 20Hz to 25KHz. The top range of pickups from the company all featured STR line contact styli, the cheapest one was the M312 III STR, then came the M315 III STR that had a quoted frequency range of 20Hz to 40KHz. While the range of the top of the line M320 III STR cartridge extended out to 45Khz.
