This article by Ron Tipton details the design and construction of the TDL Model high-performance microphone preamp, using a differential input stage that used compound transistor pairs with circuit resistance values, computer optimized for very low output noise. April 28, by Ari Polisois.

AudioXpress interview

Stamler A Power Supply Spreadsheet This article describes a spreadsheet program for designing low-voltage power supplies using common IC three-terminal regulators. In this article, Joel Hatch explains how to build a variable frequency synchronous motor controller to control turntable speed. May 8, by Ari Polisois. This article was published in audioXpress, July This article was originally published in audioXpress, June The results, as the author describes, “combine the advantage s of the push-pull mainly power to the wonderful character of the SE: This is not surprising.

This article was originally published in audioXpress, October July 25, by Pete Millett. I developed the PSU, which, together with the sophisticated shunt, sets a new standard for audio voltage regulators.


The project started with a clean sheet, looking to address potentiometer design with a quality that rivaled existing designs while maintaining a reasonable cost.

This article was published in audioXpress, April October 31, by George Ntanavaras. 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.

This article was originally published in audioXpress, December This article was originally published in audioXpress, March 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.

Sadly, the audioXpress community lost one of its most esteemed and prolific writers.

I completed the design and construction of an archival phono preamplifier, which provides variable equalization along with several other audioxpresss necessities for playing vintage records rpm discs, pre-RIAA LPs, lacquer transcription discs, and so on. This simple single-ended amp project by Pete Audioxpfess is a great performer and a very well documented project that was immediately adopted by many DIY’er’s. 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.

We think that’s more to it. February 7, by Paul J. March 21, by Ron Tipton. This article was originally published in audioxpress, March Each file has two main pages: Apart from looking at some commercially available stroboscope discs, Ron Tipton explains how to print one from files that are freely available on the Aduioxpress, and explains how to build your own multiple-LED lamp to check the rotations.


Getting the Most from THAT’s Balanced Line Drivers and Receivers

This article was originally published in audioXpress, September October 17, by Ron Tipton. In this project article for audioXpress, George Ntanavaras describes the design and construction of a high-quality Audioxpreess 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.

Now that turntables are back audkoxpress force, this excellent project not only allows some knowledge about a vital part of the motor’s rotational speed adjustment, but it also dives into one of the zudioxpress crucial aspects of a record player for anyone interested in a little DIY or restoration projects.

A PP 25L6 Amplifier In this classical tube amplifier project, author Bob McIntyre offers what is effectively the foundation for many designs that we can find currently in the market.

December 13, by Gregory L. There’s no better way to pay tribute to Ron than revisit some of these projects. The square wave is fed into a small audio power op-amp.
