Any headshell that has the standard SME screw-on connector will do.it doesn't have to be an original Technics. Just make sure it's of a weight similar to the one you have, which is 90% of the ones out there. There are a few that are extra-heavy for high-mass arms, which, if used, can make balancing the arm (and cartridge) a tad difficult.
Seems I will get a technics headshell only for being on safer side
