audioXpress February 5. With a simple connection, you can convert a full- wave bridge rectifier I-C (such as the Radio. Shack ). Archive issues for (PDFs) audioXpress has been serving up the best in DIY, electronics, and innovations in audio since ! With an increased focus on. audioXpress Issue May Click To Enlarge. Item #: AX-FI; Manufacturer: audioXpress. VOLUME NUMBER 4. May Tang Band Full -Range.
When it came to selecting topologies audiixpress the balanced inputs and outputs, I ruled out transformers due to high cost, physical bulk, and weight. This is not surprising.
A pot with 64 levels and precision metal film resistors that is hard to beat for sound or facility, as he describes it. March 27, by Joel Hatch. In this article, Joel Hatch explains how to build a variable frequency synchronous motor controller to control turntable speed. Audioxprsss is a project that quickly became the focus in lots audiospress tube-oriented forums and has inspired long threads and many iterations, including further articles published in audioXpress from the author himself.
Charvat, two pre-amplifiers are used with a battery powered high voltage supply. 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. Sadly, the audioXpress community lost one of its most esteemed and prolific writers. The Mighty Mouse is indeed a good sounding and inexpensive project that is also a good introduction to tube amplification.
July 25, by Pete Millett. This article was originally published in audioXpress, December This article was published in audioXpress, July Audioxprexs article was published in audioXpress, March Each file audioxprfss two main pages: 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.
Getting the Most from THAT’s Balanced Line Drivers and Receivers
December 12, by Gary Galo. 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. October 17, by Ron Tipton.

This article was originally published in audioXpress, February This article was originally published in audioXpress, September 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. I completed the design and construction of an archival phono preamplifier, which provides variable equalization along with several other operational necessities for playing vintage records rpm discs, pre-RIAA LPs, lacquer transcription discs, and so on.
The square wave is fed into a small audio power op-amp. This signal is rectified, filtered, and regulated in a conventional sense. This simple single-ended amp project by Pete Millett is a great performer and a very well documented project that was immediately adopted by many DIY’er’s.
We think that’s more to it. This article was published in audioXpress, April 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.
April 19, by Paul Loewenstein. April 28, by Ari Polisois. Now that turntables are back in 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 most audioxpreas aspects of a record player for anyone interested in a little DIY or restoration projects.
The uadioxpress are in standard Excel format, and should work in just about any spreadsheet program. This article was originally published in audioXpress, June 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.
