This is a particularly rigid, medium-mass tonearm with precision ball bearings and a conical tube.
The conical tube is internally damped and divided into two parts, which, while further aiding damping, also allow for easy azimuth adjustment. The vertical bearings have a highly damped brass housing, 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 blocks. Some parts are anodized and some are not, in order to help control tonearm resonance. The headshell provides a stable base for cartridge mounting, while the internally damped tube connects this to the massive bearing parts where any vibration or noise is dispersed. A special mechanism, using a simple Allen key, allows the tube to be rotated back and forth in minimal increments with no air gap, for precision azimuth adjustment. This mechanism is submerged in silicone grease for further damping. A marker line clearly shows the azimuth position and facilitates use, while allowing for repeated adjustments. 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 arm board. All bearings are preloaded and glued into position which, while damping vibration also makes them long lasting with zero play and low friction.
VTA adjustments are accomplished by raising or lowering the tonearm in the arm base. Azimuth is adjusted by releasing a locking screw and manual rotation of tube. Wiring from cartridge pins to RCA connectors is of single fixed lengths. Only high quality, Kuzma-approved wires are used in the arm, and it is also possible to order the tonearm wired in a balanced configuration.
