EI core 를 사용해서도 충분히 좋은 특성이 가능 할겁니다

 

 

제가 CD 나오기 직전에 구입해놓고 보관만한 Moving Coil Cartridge ( 현재 행방불명)

아직도 평이 좋아서 참고로 올립니다.

 

Best Phono/Turntable Cartridge under $200

When we talk about classics, we need to mention the Denon DL 103 Moving Coil Cartridge. The DL103 was designed for professional broadcast in the 60’s, using the arms and turntables of the day. There are several upgraded versions of this classical model by other companies and the Denon DL103 remains a one-of-a-kind cartridge, no matter what.

The Denon DL-103 addresses to the heavy tonearms and is a low-output phono cartridge. The output of 0.3mV needs at least 60dB of gain. This is why it needs a step up transformer for a standard MM phono preamp or phono preamp with built-in MC input.

This is a moving coil cartridge with a tracking force of 2.5g+/- 0.2g (2.3-2.7g). The microsound round tip of the stylus is great, giving amazing details for the highs and lows. The cantilever is made of aluminum and the frequency response is 20-45 kHz. The channel separation is over 25dB at 1kHz and the cartridge is only 8.5 grams.

As it’s one of the audiophile’s favorites, the Denon DL-103 combines smoothness and power, giving great sound. The cartridge gives powerful bottom end, rich midrange and silky smooth top. The tonal balance is closer to the warm side, with amazing dynamics for any kind of music or system.

The depth, mids and highs are crisp and detailed and make the Denon DL-103 a reliable choice for all kinds of audiophiles.

Our short list of pros:

  • The Denon 103 is a moving coil cartridge
  • The Denon 103 is an iconic cartridge and should exist in each audiophile’s collection
  • The sound is great, clear, crisp and detailed
  • There is huge sound stage

No matter how much we like the Denon DL-103, we still need to mention its flaws. There aren’t many, though:

  • You need to be very carefully when you set it up. Its performances depend on the setup
  • The cartridge needs a heavy tracking weight
  • The output is very low

But, for the money you pay, you not only get a classical moving coil cartridge, but also a reliable tool for your hobby.

    박사님께서 아이디어를 주셔서 1:1 단간 트랜스를 만들어 보려고 퍼말로이 코어를 구입 했었습니다.

    단간트랜스는 특성을 아주 우수하게 만들 수 있을 것으로 생각되나 직류 문제가 있어 커패시터를 같이 사용해야 할 것 같습니다. 입력트랜스 혹은 포노 카트리지 스텝업 트랜스는 박사님 말씀하신대로 구상을 하고 만들어 보겠습니다.

    스텝업 트랜스에 사용할 선을 이미 구입했습니다. 선 직경이 0.1mm 정도입니다. 선이 너무 가늘어 4줄 감기 까지 가능한 CNC 2축 자동 권선기를 구입해 연습 중입니다.

     

    진행이 되면 박사님의 지도 부탁드립니다.

     
    박사님의 아이디어 다시한번 감사드립니다.

    Trifilar 4분할 권선비 1:8 Trans 종이위에서 만드러 봤습니다.
    EZ님/다른분들도 권선/설계 구상해보십시요

    Core 전체체적 -무계- 가 작을수록 능률이 올라갑니다.
    Micro power 로 Trans 를 자화 시켜야하기 때문입니다.

    그런 측면에서 본다면 감기가 어렵지만 Toroid 가 재일 고능륭 Trans 에 적합합니다.
    다행이 Low Impedance Trans 라서 권선수가 낮습니다.
    한두개는 수동 권선도 가능할겁니다

    Step up transformer SUT-01 for the MC cartridge      120,000yen


    SUT-01 is the first step up transformer in our company.
    We are launching MC cartridge CA-1M more before in our
    company. Also, although launch the high gain equalizer amplifier
    called EQT-01 for the equalizer amplifier and came
    corresponding to the MC cartridge we went promote that
    combines it with the vacuum tube style pre amplifier aiming at
    gentler charming sound the development of the step up
    transformer as the premise.
    Recently, the launching of pre amplifier CA-02 of the vacuum
    tube style equalizer amplifier inclusion in accordance with, the
    pair with, or it made to launch as the step up transformer that is
    able to use it even alone.
    Adopting and develop a more original method an original output
    transformer in our company than before with vacuum tube style
    power amplifier etc. it has used it. Influence etc. to the sound of
    the difference, filling materials in the difference, volume line
    method, insulation materials have been accumulated as the
    know-how in the sound by the thickness of the material, the leaf
    of the core material in the process. Devising even the base and
    the like and the mounting method because it is producing
    numerously even the setting base and the like in our company
    also the highest tone quality was aimed at as the step up
    transformer.
    The step up ratio of 30 times, 10 times profitable, the input
    system is as the design that is able to match to most of the types
    about the MC cartridge that exists each as 2 systems of 1-5ohms
    and 20-40ohms.
    Adopting) 10 mm the thickness 70 mm the external form 50 mm
    (the inside diameter the large core that is thought the ring style
    core of the super permalloy that has the highest performance in
    the rate that admits the magnetism to the core material in all of
    the exception for the adoption, step up transformer we have
    gotten vast dynamic range and excellent low area characteristic.
    The thickness of the leaf that composes the core material is said
    that a high area characteristic is excellent as a generally thin
    thing. By using the pole thin material called the thiek 0.1 mm in
    this machine we have obtained an excellent high area
    characteristic.
    Adopting the Teflon that has the highest electricity insulation
    nature to the insulation paper of the volume line in every
    substance the improvement of the tone quality was
    accomplished. Because the signal level where step up
    transformer treats is extremely small the vibration control effect is
    surprised it turns up such largely. Storing the coil of the
    transformer, in the case that prevents the vibration that used
    lumber and, thick heavy brass board etc., to eliminate the
    influence of the vibration in this machine it is gluing and be fill up
    it with highly efficient epoxy resin. It is making the influence of
    small of the vibration that the transformer receives by this to the
    limit. These are contributing to the improvement largely the tone
    quality being final the one that applied the know-how in the
    development process of the setting base with at the time of the
    development of the vacuum tube amplifier of our company.
    This machine of input-output terminal to our company original
    chromium copper shaving taking out that pin Jacques obj adopt
    high tone quality and high reliability obj securing be. the an It is
    a characteristic to be worried about and be hurt the speaker
    to etc. when pin Jacques withdrew from suddenly
    because it is designed as the hot side parts previously when
    the cold side, contacts previously and draw out this pin Jacques when shine the plug.
    The appearance combines with equalizer amplifier inclusion style pre amplifier CA-02 of simultaneous launching and adopt
    the wood panel by the cherry tree material and be putting out it the unification impression of the design.
    We promote it to confirm the tone quality by the test listening by all means, because SUT-01 prepares the product

    for the test listening.


    SUT-01 Specifications

    Matching cartridge:
