More updates and details at burningamp.org and on the organizing thread at: https://www.diyaudio.com/forums/clubs-and-events/ Burning Amp 2019 will be held Saturday November 9th (Workshop Day), and Sunday November 10th, 2019 (Main Event) in San Francisco, at the Firehouse and Building C of historic Fort Mason Center. This is the 12th Burning Amp Festival, which has been occurring yearly since 2007. Founders Mark Cronander, Vladimir Simovich, and Stewart Yaniger envisioned Burning Amp as a participatory event for Do-It-Yourself (DIY) audiophiles to show off their projects, learn, network, and share their passion for experimenting with DIY audio gear. Burning Amp has remained true to this vision and is an all volunteer non-profit audio happening supported by our enthusiastic community. The Sunday Main Event will feature two Keynote speakers: Sean Casey, founder of audiophile speaker manufacturer Zu Audio, and audio industry (and DIY) legend Nelson Pass. The Burning Amp participants will display and audition their DIY projects. The Saturday Workshop Day will include separate speaker and amplifier workshops. In the amplifier workshop participants will build an audio component of their own (design in progress). 2019 Keynote Speakers: Sean Casey: Sean is the Founder of Zu Audio. Since 2000 Zu has produced “made in the USA” high-value, affordable, high-efficiency music systems for the audiophile without a bottomless wallet. Zu uses original concepts and engineering to restore aliveness and realistic fidelity to playback. Nelson Pass: One of the most enthusiastic members of the DIY community has been legendary amplifier designer Nelson Pass. Mr. Pass has also been supporting audio hobbyists for decades. In 1977 he published plans for the A20, a single-ended Class A amp. In 1994 he published plans for the Zen amp, and Bride of Zen pre-amp, radically simple designs which attempt to answer the question, “What is the sound of one transistor clapping?” In the 25 years since, he has made multiple further variations on that theme. In addition to his main company Pass Labs, in 1998 Nelson Pass formed FirstWatt to explore unusual amplifier designs in neglected areas. The resulting low-powered amplifiers achieve very high quality with simple Class A circuits and little or no feedback. One of those, the Firstwatt J2, was Stereophile’s 2016 Amplification Component of the Year. Hours are 1pm to 8pm on Saturday. (Pre-registration for Saturday will be required.) Sunday hours are 9:30am to 8pm. A catered Indian buffet lunch will be available on Sunday. Coffee and snacks will be provided both days. Weather in San Francisco in November is usually quite pleasant although rain is possible. All are encouraged to attend and to become part of our community. Bring your project, whether a breadboard prototype or a beautiful example of audio art.

  3. Take a look at the Bottlehead Quickie battery powered tube preamp. Only $99 batteries not included. Easy and fun to build, moron proof assembly instruction. Great sounding.
  4. The 6dn7 tubes are used in the Bottlehead SEX 2 and 2.1 amps.
