I have an early SME 3009 as well. I checked my manual and the counterweight should be adjustable (not fixed). Perhaps a little heat from a heat gun or blow dryer would be enough to free it up.
I have a Ortofon 2M Bronze on my SME (on a Technics SL1200 Mk. 5) and it's a great sounding and tracking match.
Good luck!
