Jakutis turntables are made from high quality materials: stainless steel, bronze, brass, granite, specific woods, processed using the latest technology (cnc machining, plasma coating and others). The selection of all technical solutions is based on the given acoustical requirements. Serious consideration is given to the appearance of the turntable, as a good-sounding turntable must be also be a good-looking object in the user’s home.


Basic Concept of Jakutis Design

A very heavy table utilizing spherical rubber dampers to support a heavy sub-chassis. The sub-chassis carries a heavy platter as well as the tonearm. This assembly (the tonearm,platter and sub-chassis) constitute a single, independent structure, floating on spherical dampers. A low-power but extremely stable synchronous motor is located on the table and drives the platter via a belt.

Turntable Core Parts

1. Stand and Table:

Some turntables ( Stork and Dalia, for example ) have legs, because they are heavy , thus they do not require additional stands or tables. The legs are made of stainless steel tubes, filled with acoustic damping material. The stands can be leveled by tuning the spiked feet of each leg. The legs support a 60mm (Dalia, Milky Stork) or 40mm (Black Stork) thick table, measuring 470x 470mm and made of granite . The lower part of the legs is combined 30mm (Dalia, Milky Stork) or 20mm (Black Stork) thick granite panel. The foot spikes sit on flat pads.

2. Sub-chassis:

All turntables have one of two types of sub-chassis : conical, made of marble with triangular frame ( Milky Stork, Black Stork, Dalia ) or plate-type, made of granite ( Starling, Ouzel ). A triangular frame is made of stainless steel tube which is then filled with an acoustic damping material. Marble was chosen because for its good acoustic and mechanical properties. Plate type granite can be made of Matrix Anticato (Starling). This naturally occurring composite stone was formed during the cooling of molten lava, and has a laminated structure; it is well suited to the damping of ambient vibrations. The plate-type sub-chassis (see Emu ) can accommodate two or three tonearms.

3. Suspension:

The sub-chassis rests on spherical elastic dampers which in turn rest on machined bronze supports. The height of each support can be adjusted to level the platter. The dampers themselves, being spherical, absorb shock from all sides equally. Dampers of varying elasticity are available and are easily replaced.

4. Magnetic Bearing:

The bearing is a classic type – a 9mm steel shaft within a steel sleeve. The outer surface of the shaft and inner surface of the sleeve are precisely polished. The difference is that tip of shaft rests not on steel or ceramic ball, as usual, but on magnetic pillow, created by two neodymium magnets. This eliminates hard mechanical thrusts between the shaft and bottom of bearing and reduces vibrations of the platter. As the diameter of magnets is only one inch and the distance to tonearm is long, this does not affect the cartridge. The assembly is located in a 35mm diameter stainless steel housing that is filled with oil.

5. Motor:

The platter is driven by a low-speed (250 rpm) synchronous Crouzet motor, mounted to 5 a kg bronze body in a stainless steel housing.

6. Platter:

The platter can be made of brass, brass with acrylic insert, aluminum with acrylic insert. Diameter of platter – 320mm , weights about 10 kg.
