2-Speed Belt-Drive Turntable
synchronous constant speed motor
The Connoisseur BD1 turntable is a precision engineered product expressly designed to provide a top grade no compromise performance at a modest cost.
Operating at 33.33 and 45rpm, it incorporates a unique flexible belt drive system virtually eliminating vibration and transmission noise.
A slow speed synchronous motor which has a very low hum field is used thus making the unit suitable for use with even the most sensitive pickups.
Performance and reliability being the main criterion, complex mechanisms have been avoided.
Speed change is accomplished manually and can be affected in seconds - a hinged top plate at the rear of the platform facilitates this operation.
The turntable platter is a non-ferrous aluminium casting precision lathe turned to fine limits.
All running shafts are of high quality carbon steel, lapped and polished with diamond dust to a mirror finish.
The main turntable bearing is of phosphor bronze and incorporates a hard steel thrust ball reducing friction and wear to a minimum.
Featuring slim line construction the BD1 requires only 2" of space below the mounting platform.
