Kuzma Stogi Tonearm

Unique feature: Most parts are glued together for rigidity and damping. We use very precise stainless steel ball bearings same as used in gyroscopes precisely mounted with zero play and very low starting and running friction and noise levels. Each bearing from the factory is vacuum sealed with a serial number for quality control. Each bearing's load is  20 kg. Two are used for vertical and two for horizontal movement.

This is a very rigid medium mass tonearm with precision ball bearings which, while withstanding very heavy loads, displays extremely low starting and running friction and noise levels. The main frame and all other parts are machined from solid aluminum and brass blocks. Some parts are anodized and some are not, to help control tonearm resonance. The headshell provides a stable cartridge mounting, while the internally damped tube connects this to the massive bearing parts where any vibration or noise is dispersed. Most parts are glued together for rigidity and damping.

A straight tube is machined from an aluminum rod fixed on brass support to increase tube damping.
Azimuth is adjusted by releasing a locking screw and manual rotation of the tube on brass support.
  
A decoupled brass counterweight controls balance and adjusts tracking force while damping vibration in the tube. The massive arm base serves to clamp the tonearm rigidly to the armboard. All bearings are pre-loaded and glued into position which, while damping vibrations in them, also provides long-lasting, zero play, low friction, and low noise level in the bearings. VTA adjustment is made by raising or lowering the tonearm in the arm base itself.   

Wires are in one length from cartridge pins to RCA connectors. High-quality wires are incorporated into our cable. It is also possible to use the tonearm in a balanced ( XLR) or 5pin configuration.
