Condition Details

• Microscope Inspection: Stylus was inspected using a Shure SEK-2 Microscope—shows no visible wear. 
  
• Stylus Condition: Clean stylus cantilever with straight alignment and plenty of tip life remaining (see photos for detailed close-ups).
  
• Channel Separation: Excellent channel separation measured with a Fozgometer at 40dB!
  
• Tracking Performance: Successfully passed tests using the Ortofon Test Record, tracking up to 90 µm lateral amplitude (315 Hz modulation frequency) with zero audible distortion.
  
• Cosmetic Condition: Excellent overall. Please note a very minor, cosmetic mark on the side near the mounting bolt (resulted during installation), which is not visible once mounted and does not affect performance in any way.
  
• Functional Condition: Tested and working wonderfully. The cantilever is straight, and the stylus tip is in great shape, offering clean, distortion-free playback.

Setup Notes: Currently mounted and aligned on a sought-after SAEC headshell. It requires a phono stage or step-up transformer capable of handling low-output moving coil cartridges, or a phono preamp set to around 40dB to 60dBof gain depending on your system matching).
