B790

About the B790

The Revox B790 is a vintage stereo turntable featuring a quartz-controlled direct drive motor and a unique tangential (linear tracking) tonearm with opto-electronic servo control. It offers speeds of 33 1/3 and 45 rpm with a speed accuracy of ±0.01% and manual speed variation of approximately ±7%. The tonearm is pneumatically damped and electronically muted until the stylus contacts the record, reducing wear and distortion. The turntable has a 312-313 mm diameter platter weighing about 1.1 kg, with a run-up time under 2 seconds at 45 rpm and braking time under 1.5 seconds from 45 to 33 1/3 rpm. It achieves wow and flutter better than 0.05% (weighted) and a signal-to-noise ratio better than 65 dB. Originally equipped with an AKG P 8 ES cartridge, some units come with Elac 795 or Grado Silver MM cartridges. The B790 was manufactured in Switzerland between 1977 and 1983, weighs approximately 11 kg, and measures 452 x 142 x 382 mm (WxHxD). It is noted for its advanced design that eliminates skating distortion and maintains a constant lateral tracking angle, providing high fidelity playback.
