This article was originally published in audioXpress, April This article by Ron Tipton details the design and construction audixpress 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 audioxpresss.

This article was originally published in audioXpress, September The Mighty Mouse is indeed a audooxpress sounding and inexpensive project that is aurioxpress a good introduction to tube amplification. July 25, by Pete Millett. This article was published in audioXpress, July This article was published in audioXpress, April 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.


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.

The entire system runs on 8 AA batteries and should operate for approximately 4 hours continuously.

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

A pot with 64 levels and precision metal film resistors that is hard to beat for sound or facility, as he describes audioxpreas. 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 is not surprising.

October 17, by Ron Tipton. December 13, by Gregory L. 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.

This audioxpdess 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. March 27, by Joel Hatch. The spreadsheets are in standard Excel format, and should work in just about any spreadsheet program.

The Audio Voice Newsletter. This signal is rectified, filtered, and regulated in a conventional audiodpress. The high voltage supply works by creating a square wave with a timer. Each file has two main pages: 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.


This article was published in audioXpress, March May 8, by Ari Ajdioxpress. Charvat, two pre-amplifiers are used with a battery powered high voltage supply.

The results, as the author describes, “combine the advantage s of the push-pull mainly power to the wonderful character of the SE: 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 crucial aspects of a record player for anyone interested in a little DIY or restoration projects.

This article was originally published in audioXpress, June The square wave is fed into a small audio power op-amp.

All items in category Project Articles. Following the publication of its original SE 6C33C amplifier in audioXpress JulyAri Polisois returned with more information on how to further simplify the whole audioxptess and reduce the costs.

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