Technical characteristics of PCUHD.
This material eliminates inclusions and impurities through a combination of a casting process that does not use any refractory and a post-processing processn 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.
Original F e a t u r e s :
- Bearing for vertical direction equipped super steel metal KNIFE EDGE system.
- 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.
- 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 create good reproduction sound.
- The tonearm geometry allows for a Baerwald alignments which is IEC recommendations.
- This universal type counterweight can be used from 17 to 35 grs cartridge weight including head shell.
- TK-850M is fitted with a standard head shell and can easily be changed with other standard head shell (cartridge).
- This attached head shell can adjust the azimuth angle of the cartridge.
