Do remember that you are liable for import duty and local VAT or other taxes.


Heavier weights are available, particularly for SA-750L versions, please enquire.

PLEASE NOTE XTC is bulkier and wider than the original counterweight. It is assumed the Jelco arm is mounted with the stub in line front to back.

THE DESIGN of XTC places its lowered Centre of Gravity closer or below the plane of the stylus tip, depending on your cartridge height. This better matches the rotational forces imposed on the cartridge which should improve tracking.
Other dropped counterweights may manage to lower CG by up to 10mm.
Factor in the other masses, and overall CG reduces this to ~7mm which is some distance ABOVE the stylus. 
XTC lowers CG by up to 16mm.


This counterweight defintely improved music reproduction as claimed
