The tonearm serves as the second cartridge.

Jelco is now unable to accept new orders from April 2nd, 2020, due to the availability of transportation and delays in production due to the spread of the serious infectious disease new coronavirus.
Thank you for your understanding.

aik_0115.jpgThe most important thing in improving the quality of sound in an analog audio system is determined by how the output signal of the tonearm including the cartridge can be extracted. aik_0125.jpgJELCO considered the theme of “0” friction as a tonearm producer.
The answer was a one-point cross suspension and the introduction of a mechanical mechanism with a newly developed knife-edge structure. (TK series)
aik_0143.jpgThis time, in order to commemorate the 100th anniversary of our founding, we aimed to further evolve the tonearm and focused on the signal system. aik_0135.jpgA high-purity oxygen-free copper wire PCUHD has been newly developed for the tonearm inner wire that contains less than half the amount of oxygen contained in the OFC conductor, and its adopted for the first time in the world. aik_0147.jpgIn addition, thick high-purity silver (equivalent to more than 4N) is plated on this PCUHD wire to further add sound transparency and resolution.

The tonearm serves as the second cartridge.

Features Menu

 

PCUHD (Inner Cable) Rhodium plated (TK series) Rhodium plated (TK series) Rhodium plated (TK series) TS series  

  • Designed Hi-mass type system, and deferent kind  metal material used for anti vibration, those are very low gravity, and low gravity sound created from this.
  • Simple mechanism is good reproduction sound create.
  • The tonearm geometry allows for a Baerwald alignments which is IEC recommendations.
  • Universal type counterweight equipped from 17 to 35 grs cartridge with headshell applied Lighter cartridge can be used when headshell weight installed.

Knife Edge bearing (TK series)

Knife Edge bearing (TK series)

 

This Knife Edge material is specially made of super steel, and have very stable and smooth operation. This Knife Edge is precision hand made, and result is to have very low friction.

 

Universal Type Counterweight

Universal Type Counterweight

 

This very unique structure of counterweight is to set up lighter to heavier cartridge without to change counterweight it self.

 

  • This material eliminates inclusions and impurities through a combination of a casting process that does not use any refractory and a post-processing process that does not pass through hot extrusion and rolling processes.
  • Despite being a 4N (copper purity 99.99%) grade material, it has the characteristics of "high flexibility" and "drawability that can be processed to ultra fine wires".
  • Among the impurities, oxygen that is particularly likely to be mixed could be suppressed to below 5 ppm, which is below the standard for general oxygen-free copper wires. It is unnecessary to use a gas burner in the process by filling the inside of the apparatus with an inert gas.
  • PCUHD stands for Pure Copper Ultra High Drawability
    • Characteristics:
       By combining a molding process that uses no heat resistant materials with post-processing free from hot extrusion or rolling processes, the product can be mass-produced in a way that excludes inclusions and impurities. While the product is a 4N grade material (copper purity 99.99%), it possesses high malleability and drawability that allows processing up to superfine wires.
       Oxygen is one of the most common impurities in copper products. For this reason, no gas burners are used during the manufacturing processes and the insides of the equipment are filled with noble gases.
       Through these methods we have succeeded in controlling oxygen to 5ppm, which is below the standard required for oxygen-free copper.
