I picked up the 3009 II improved from my mate last night, its hardly been used and has been living in his loft for the last 10 years! Anyway, as you would imagine its in pretty fine condition except the bias weight is missing anybody know where I can get these or do I just go back to SME? Also, along with the arm he's let me have various protractors etc, one is from a company called EEI and was purchased in the 70's. This involves detaching the headshell and inserting this plastic gauge, anybody know anything about them? Finally, it has two headshells, ones a standard SME and anothers got the inscription AER, AOR or something along those line (ive not looked properly yet). My mate seem to rate the latter but whats the thoughts on that??
