Getting the Most from THAT’s Balanced Line Drivers and Receivers
Charvat, two pre-amplifiers are used with a battery powered high voltage supply. A pot with 64 levels and precision metal film resistors that is hard to beat for sound or facility, as he describes it. All items in category Project Articles. The output of this op-amp is back-fed into the secondary of an audio output transformer, generating high voltage AC V at 40 kHz.
The author describes a microphone amplifier designed to interface a standard dynamic microphone to a soundcard or other computer microphone input with a 5V through 2.
In this article, Joel Hatch explains how to build a variable frequency synchronous motor controller to control turntable speed. April 28, by Ari Polisois.
May 8, by Ari Polisois. This is not surprising.
This is a project that quickly became the focus in lots of tube-oriented forums and has inspired long threads and many iterations, including further articles published in audioXpress from the author himself. A PP 25L6 Amplifier In this classical tube amplifier audjoxpress, author Bob McIntyre offers what is effectively the foundation for many designs that we can find currently in the market.
This article was originally published in audioXpress, December Each file has two main pages: This article was originally published in audioXpress, October Apart from looking at some 200 available stroboscope discs, Ron Tipton explains how to print one from files that are freely available on the Internet, and explains how to build your own multiple-LED audioxpreess to check the rotations. This article from respected author Ari Polisois deals with a single-ended amplifier with enough power to drive even the most difficult speaker systems – delivering 50W per channel.
Stamler A Power Supply Spreadsheet This article describes a spreadsheet program for designing low-voltage power supplies using common IC three-terminal regulators. Following the publication of its original SE 6C33C amplifier in audioXpress JulyAri Polisois returned with more information on how to further simplify the whole construction and reduce the costs. The Mighty Mouse is indeed a good sounding and inexpensive project that is also a good introduction to tube amplification.
There’s no better way to pay tribute to Ron than revisit some of these projects. The high voltage supply works by creating a square wave with a timer. October 17, by Ron Tipton.
This article was originally published in audioXpress, March This article was originally published in audioXpress, September This article was originally published in audioxpress, March We think that’s more to it. This article was originally published in audioXpress, February March 21, by Ron Tipton.
July 25, by Pete Millett. The spreadsheets are in standard Excel format, and should work in just about any spreadsheet program.
The square wave is fed into a small audio power op-amp. The Audio Voice Newsletter.
In this article, Ron Tipton explores the use of stroboscope discs to determine whether your turntable is set to the correct rotational speed. December 12, by Gary Galo. December 13, by Gregory L. In this project article for audioXpress, George Ntanavaras describes the design and construction of a high-quality RIAA preamplifier for moving coil cartridges based on high-quality Analog Device AD op-amps designed for low-noise audio applications and driven from very low source impedance.
