General information [contribute]

Allaerts web site (December 9, 2009): A cartridge transforms micro mechanical movements into an electrical tension.We are talking about micromechanics since these systems are trying to convey these movements into electricity under very extreme conditions,enormous concentrations of mechanical strain and magnetic energy fields.The fact that one can go about these in several different ways is well kown and the moving coil principle is only one of many options. The latest developments in this specific technology showed clearly that it warrants the highest quality feasable.

The drawbacks being mostly its lowish output requiring especially sensitive amplifiers. Due to the variety and complexity of its many orders Allacor increased its research in the field looking for answers on the precise composition and relational behaviour of parts and materials used in a cartridge. We found that to build an exceptional cartridge one needs to pay attention so such details as the molecular structure of the materials used and moreover that the internal electrical potentials within these materials can hinder the energy carriage within the entire system.

Therefore it should be said that it soon became clear that some opposing and correlating demands within the system were to be met. One part of major importance is the housing,the so called shell,which has to be made of a very soft grade of aluminium which is then to be coated with an extremely resistent conductive oxyde coating. The systems polar shoes are carved out manually,not machined nor pressed,as to not upset its molecular structure.Also the magnet is picked from a rare earth material with constant magnetism,in such a way that it is not influenced by a changing magnetic field.

These three elements,the housing,polar shoes and magnet,once finished are then fitted together with a precision of one thousandth of a milimeter. A presicion that can only be achieved by working under a microscope using specially made tools.

The coils which generate the electrical field are wound by hand and subsequently fixed at the center of the magnetic field.The coilwire used can be either copper,silver or gold depending on the type of cartridge to be built. And again this system is placed with a precision of one thousandth of a milimeter,diagonally crossed onto the magnetic field. Depending on the type of cartridge model a cantilever made out of boron,saphire or diamond is fitted which is carrying the tip.This is either a Fritz Gyger type 1 or S and has an expected life of five thousand playing hours.Tip and cantilever are again mounted with a precision of one micron in line with the housing.

Now the cartridge is ready to be sealed with an extremely thin aluminium shell which is goldfoil plated on the inside using twenty four carat gold. This gets connected to the earthing system to provide a cage of Faraday and thereby creates a perfect low an high frequency shield.

History[contribute]

Allaerts web site (July 7, 2009): It was back in 1978 that the company was founded by J.Allaerts. At first the company lended its services to the retailers by doing repairs on various audio and video hardware.

Over the years, the company focused more and more to the field of repair and maintenance of micro mechanical parts on several parts of cartridge systems.

By doing so an enormous amount of know-how could be gathered but moreover all these special techniques could be integrated into an consistent insight.

So the company soon got reknowned worldwide for its top level moving coil cartridges competing with the very best available.
