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.
