The TecnoArm(a) is a fundamental mechanical rebuild of the well-known RB250 tonearm, to which is added monolithic wiring of the highest quality. The arm tube is bead-blasted and perforated, which disperses structural resonances and yields a lower effective mass. The arm wand is internally damped to reduce resonance further, and the headshell is machined flat, to allow true azimuth relative to the bearing craddle. After modification the bearings are re-adjusted for highest possible performance, according to original Rega procedures.
