This is a 12 inch version of Stogi S unipivot tonearm.
It is a unipivot bearing design with a unique, rigid square headshell made from a solid aluminium block and a base of solid brass which control all vibration and facilitate stability of the tonearm as a whole. All parts of the arm are machined from blocks of solid metal, in order to provide damping and minimise resonance. The polished pivot point is sited in an oil well, which provides extremely low friction and bearing vibration. The bearing height is at record level for optimum tracking. The silicone damping controls resonance of the cartridge and also gives stability in azimuth direction.
Two counterweights allow easy adjustments of tracking force and azimuth. Fine azimuth adjustment is achieved by rotation of a horizontal screw in the main counterweight, which does not affect other tonearm parameters and which makes fine azimuth adjustment very simple.
