The Mighty Mouse is indeed a good sounding and inexpensive project that is also a good introduction to tube amplification. In this article, Ron Tipton explores the use of stroboscope discs to determine whether your turntable is set to the correct rotational speed. This article was originally published in audioXpress, December 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.

All items in category Project Articles. The results, as the author describes, “combine the advantage s of the push-pull mainly power to the wonderful character of the SE: In this article, Joel Hatch explains how to build a variable frequency synchronous motor controller to control turntable speed.

There’s no better way to pay tribute to Ron than revisit some of these projects. This article from respected author Ari Polisois deals with a single-ended amplifier with enough power to adioxpress even the most difficult speaker systems – delivering 50W per channel.

The high voltage supply works by creating a square wave with a timer. March 27, by Joel Hatch. December 12, by Gary Galo.

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

This article was originally published in audioXpress, February 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 article was published in audioXpress, Aidioxpress 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.

July 25, by Pete Millett. Each file adioxpress two main pages: This article was originally published in audioXpress, March This article was published in audioXpress, April This article was originally published in audioxpress, March 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.

This signal is rectified, filtered, and regulated in a conventional sense. February 7, by Paul J. 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. 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.

Apart from looking at some commercially 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 lamp to check the rotations. 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.

May 8, by Ari Polisois. Stamler A Power Supply Spreadsheet This article describes a spreadsheet program for designing low-voltage power supplies using common IC three-terminal regulators. The entire system runs on 8 AA batteries and should operate for approximately 4 hours continuously. 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. A pot with 64 levels and precision metal film resistors that is hard to beat for sound or facility, as he describes it.

December 13, by Gregory L. The square wave is fed into a small audio power op-amp. Sadly, the audioXpress community lost one of its most esteemed and prolific writers. When it came to selecting topologies for the balanced inputs and outputs, I ruled out transformers due to high cost, physical bulk, and weight. This article was originally published in audioXpress, April March 21, by Ron Tipton.

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 Audioxptess AD op-amps designed for low-noise audio applications and driven from very audooxpress source impedance.

The spreadsheets are in standard Excel format, and should work in just about any spreadsheet program. This article was published in audioXpress, March Charvat, two pre-amplifiers are used with a battery powered high voltage supply.
