OHMITE AUDIO GOLD 10W 電阻筆記

 OHMITE AUDIO GOLD 10W 電阻筆記

網路上買了幾支OHMITE AG系列,我是買來準備用在300B上及6AS7管機上。實際聽感後補。

Ohmite AG10 Audio Gold 10W - 15 Ohm. Size (LxD): 45,2x10,3mm. Voltage: 1000V. The Ohmite AG10 Audio Gold resistor has been designed for high-end audio amplifier and speaker applications. These resistors utilize high quality resistance wire, wound on a ceramic core, terminated, and finished with flameproof Centohm coating. The use of non-magnetic materials improves sound quality.
Audio Gold resistors are designed for use in cross-over networks and as source, emitter, or cathode resistors in balancing applications for output transducers

Features:

Non-magnetic materials

  • Mono-metallic design
  • Welded connections
  • Reduces signal distortion
  • Minimizes thermal EMF
  • Reduces current noise
  • Superior mid-range frequency performance
  • Improved stability

    Specifications:

  • Resistor material: copper-nickel
  • Core: Ceramic
  • Coating: Centohm
  • Terminals: copper-nickel
  • Electrical tolerance: 5%
  • Temperature Coefficient: 50ppm/'C
  • Overload: 10x rated power for 5 sec.
  • Derating: Linearly from 100% @ 25'C to 0% @ 275'C
  • 跟據sandy測試的結果,用在45的管機上, 低頻要比DALE金殼多出太多了,有點嚇到, 樂器聲也清楚很多, 在屏級電阻上聲音純淨度也非常高, 跟VISHAY BC綠色10W的那種電阻要好聲很多 。

    另外是原廠廣告的部分內容:
