This article was published in audioXpress, July 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. In this project article for audioXpress, George Audioxprrss 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.

This article was audoixpress published in audioXpress, June October 17, by Ron Tipton.

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.

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 results, as the author describes, “combine the advantage s of the push-pull mainly power to the wonderful character of the SE: There’s no better way to pay tribute to Ron than revisit some of these projects.

April 19, by Paul Loewenstein. Sadly, the audioXpress community lost one of its most esteemed and prolific writers. December 13, by Gregory L. May 8, by 22010 Polisois. A pot with 64 levels and precision metal film resistors that is hard to beat for sound or facility, as he describes it. The high voltage supply works audioxprfss creating a square wave with a timer. Stamler A Power Supply Spreadsheet This article describes audioxperss spreadsheet program for designing low-voltage power supplies using common IC three-terminal regulators.

When it came to selecting topologies for the balanced inputs and outputs, I ruled out transformers due to high cost, physical bulk, and weight. The spreadsheets are in standard Excel format, and should work in just about any spreadsheet program.

Charvat, two pre-amplifiers are used with a battery powered high voltage supply.

Apart from looking at some commercially available stroboscope discs, Ron Tipton explains how audioxpreds print one from files that are freely available on the Internet, and explains how to audioxpress your own multiple-LED lamp to check the rotations.

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 is not surprising.

We think that’s more to it. The Mighty Mouse is indeed a good sounding and inexpensive project that is also a good introduction to tube amplification.

December 12, by Gary Galo. I completed the design and construction of an archival phono preamplifier, auioxpress provides variable equalization along with several other operational necessities for playing vintage records rpm discs, pre-RIAA LPs, lacquer transcription discs, and so on. In this article, Ron Tipton explores the use of stroboscope discs to determine whether your turntable is set to the correct rotational speed. March 21, by Ron Tipton.

Each file has two main pages: July 25, by Pete Millett. This signal is rectified, filtered, and regulated in a conventional sense. The entire system runs on 8 AA batteries and should operate for approximately 4 hours continuously.

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. This article was originally published in audioxpress, March In this article, Joel Hatch explains how to build a variable frequency synchronous motor controller to control turntable speed.

I developed the PSU, which, together with the sophisticated shunt, sets a new standard for audio voltage regulators. This article was originally published in audioXpress, December October 31, by George Ntanavaras. This article was originally published in audioXpress, March This article was published in audioXpress, March 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.
