A manifesto for Audio DIY-ers

by Jan Didden

本文地址:http://www.animayayuda.com/archive/articles/
文章摘要:diyAudio ,王振民认为,一方面,研究此领域难以发论文,很多人都转研究方向了;另一方面,焊接电源涉及多学科领域,其控制方法与实际的焊接工艺过程密切相关,有较高的技术门槛,研究和应用都需要长时间积累,但近十多年,国内不少高校的焊接专业已被取消,用人单位对焊接的重视程度也不够,待遇差,导致了人才储备远远不足。此外,东西湖区花样年花样城楼盘因“电梯坠亡”事故引发舆论围观,后期还需注意形象修复。  清华大学附属北京清华长庚医院骨科主任医师潘勇卫:第一就是保持良好的生活习惯。,  另外还要提醒参加婚礼的人,遭遇了低俗闹婚行为侵害时,要及时保存证据,如视频、音频、证人证言、伤情鉴定报告、治疗单据等等,以便日后报警或者起诉维权。  “实现党在新时代的强军目标、把人民军队全面建成世界一流军队,我们还有许多‘雪山’‘草地’要跨越、许多‘娄山关’‘腊子口’要征服。看,年年维持在千万量级,每年都小幅成长10多万,是不是“好棒棒”?  乍看之下很漂亮,但数字里充满水分:旅行公会全台联会理事长萧博仁直言不讳地说,堆出来的数字没有意义,当局在统计过程中存在重复计算、牵强附会的问题,连过境旅客和外劳移工都算在了里面。。

A great piece that will ring true for anyone who has a passion for do-it-yourself audio. Based on an editorial that was written over 30 years ago, it shows that some things in this hobby change, and some things never will!

Amp Camp Amp #1

by Nelson Pass

Do-It-Yourself audio is a great activity. Many major audio components are easily constructed and made to perform as well or better than what we see in the stores and at considerable savings. The process is educational and therapeutic and there are few greater satisfactions than listening to music on equipment you have built yourself.

L扐mp: A Simple SIT Amp: Part Deux

by Michael Rothacher

In the first L扐mp article, we built-up a simple Class A amplifier using a not-quite unobtainable Static Induction Transistor. It抯 a nice amp, but it doesn抰 have a lot of power or voltage gain. In this little vignette, we抣l examine a simple option for improvement.

L扐mp: A Simple SIT Amp: Part 1

by Michael Rothacher

I抦 not a real amplifier designer, and this is not a real article about a wicked-good sounding, super-simple amplifier anyone can build using light bulbs and alien technology. Now that the pressure抯 off, we can have a little fun.

Burning Amplifier BA-3

by Nelson Pass

In the BA-1 and BA-2 projects we constructed two different amplifiers using very similar input and voltage gain stages (aka the 揻ront ends?, but used them to drive two different Class A Mosfet follower output stages. Now we are going to flip this approach and begin exploring some different front end designs capable of driving these and other follower output stages.

What is Gain Structure?

by Michael Mardis

Gain structure is a concept that gets talked about a lot in pro audio, but most home audio folks have never heard of it. Understanding gain structure can help you get the cleanest signal possible out of your system and avoid some nasty things like noise and clipping.

Midwest Audio Fest

by Michael Mardis

"There they were, dozens of pairs of beady tweeter eyes, flared midrange nostrils, gaping woofer mouths ?all daring us to say something, anything, good. I was trapped in a room surrounded by forty plus pairs of speakers, all waiting to sing and be judged. Some of them hulking as big as a Frigidaire, some so small that two would fit in your hand, others looked like fish or sewer pipes, race cars, Uncle Sam or even a puppet piano face. No kidding. Fortunately they didn't all sing at once!" Want to know what it's like to be in a hotel meeting room surrounded by more than 40 pairs of handmade speakers? Read on...

His Master's Noise: A Thoroughly Modern Tube Phono Preamp

by Stuart Yaniger

SY decided to just chuck his phono preamp and build a new one from scratch. The old one, a hybrid tube-FET cascode design, suffered from less-than-optimal noise and distortion, insane power supply sensitivity, and OK-not-great RIAA conformance, so the new one is designed to be better in all those respects. This article describes the theory, design, and construction of an excellent phono preamp.

Audio Component Grounding and Interconnection

by David Davenport

There is a lot of information available for designing audio circuits, but precious little on interconnecting those circuits into a total audio system to achieve maximum performance. This article focuses on audio system design for the DIY enthusiast implementing a system for home use and will most benefit the person constructing his or her own equipment.

Arpeggio Loudspeaker

by Morgan Jones

This article follows the design process from theory to measurement of a loudspeaker engineered to be driven by a low powered single-ended triode amplifier. The author has a broadcast background, so accuracy was a key requirement. This is not a loudspeaker designed to sound 搉ice? it is a loudspeaker engineered to sound 搑ight?

De-Lite Amplifier

by Nelson Pass

Many of you have never built an amplifier, and this article is intended to get you to do it. One of the biggest hindrances is the hesitation to take that leap into building your own electronics. ... The solution: choosing something really easy but satisfying ?a simple but exotic project with low barriers and cheap satisfaction.

Burning Amp Festival 2009

by Jan Didden

We failed again at Burning Amp 2009: No amplifier actually burst out in flames, but one did smoke a lot... Mark (Variac) was nervous. So was everyone around him. Burning Amp 2009 had arrived... What would the weather be, would we have enough food and enough tables? But most importantly: would there be enough interesting visitors with interesting stuff to make it a success? Read on and find out ...

Burning Amplifier BA-1

by Nelson Pass

The Burning Amp Festival happens every end of year in San Francisco. Do-it-yourself audio enthusiasts from all over gather to listen to talks and equipment demos, show off their projects, and rub shoulders with the rich and famous. Having a very large collection of audio parts and diminishing storage space, I seem to have fallen into the role of Santa Claus there, distributing components and cheap advice, with white hair, beard and a large elf (Colin Pass) to add verisimilitude. This year we also brought a batch of unfinished amplifiers - chassis, connectors, transformer, power supply capacitors and Mosfet output stages. As we were handing these out, it became apparent that a suitable design for their use was a requirement, so the notion of the Burning Amps was born, a series of Class A designs which run fearlessly hot in the pursuit of quality amplification. Here is the first one.

Burning Amplifier BA-2

by Nelson Pass

In Burning Amp 1 we examined an amplifier circuit designed to complement the hardware we gave away to some attendees at last October's Burning Amp Festival in the San Francisco bay area. This first design centered on a power output stage having of four banks of parallel N channel Mosfets. It was a single-ended Class A amplifier which delivered high quality sound with only local feedback. Burning Amp 2 will use virtually the same front end and power supply but coupled to complementary banks of N and P channel power Mosfets used as followers in a push-pull Class A configuration. Introducing ... Burning Amp 2!!
