Burning Amp 2017 Will Be The Biggest and Best Ever!

Burning Amp, the event for people interested in making or learning about do it yourself audio equipment, auditioning equipment made by others, and attending talks concerning various audio topics, will return November 12 to San Francisco. It is not necessary to bring components to show in order to attend Burning Amp, but admission is free for those who do. So, this is a great opportunity for those whining to show something they’ve made to be auditioned or admired!

Stuart Yaniger wrote a great article for audioXpress in February 2009, The ImPasse Preamplifier, describing a tube preamp to drive a pair of Nelson Pass’ First Watt F4’s (or other low-to-unity-gain power amplifiers) in balanced mono. Yaniger’s preamp is truly an elegant design with very, very low distortion, using a 6SN7 to drive a 6922 in balanced mode. There are LED’s, NE2H neon lamps and depletion MOSFETs in the design.

With little time to present a project for the annual Burning Amp Festival (BAF) in San Francisco, CA, Michael Rothacher decided to do a preamplifier project using static induction transistors (SITs). He wanted a versatile preamplifier that would work well in a variety of situations, and which could fit conveniently in a suitcase. This article was originally published in audioXpress, April 2014.
