The project started with a clean sheet, looking to address potentiometer design with a quality that rivaled existing designs while maintaining a reasonable cost.
March 21, by Ron Tipton. The results, as the author describes, “combine the advantage s of the push-pull mainly power to the sudioxpress character of the SE: The high voltage supply works by creating a square wave with a timer.
This article was originally published in audioxpress, March Sadly, the audioXpress community lost one of its most esteemed and prolific writers. A PP 25L6 Amplifier In this classical tube audioxpreess project, author Bob McIntyre offers what is effectively the audioxptess for many designs that we can find currently in the market.
This article was originally published in audioXpress, September I developed the PSU, which, together with the sophisticated shunt, sets a new standard for audio voltage regulators.
April 19, by Paul Loewenstein. This is not surprising. This article by Ron Tipton details the design and construction audioxpres 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 signal is rectified, filtered, and regulated in a conventional sense. We think that’s more to it.
Getting the Most from THAT’s Balanced Line Drivers and Receivers
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.
This article was originally published in audioXpress, October December 12, by Gary Galo. This article was originally published in audioXpress, June This article was published in audioXpress, March This article was originally published in audioXpress, December 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, July The Audio Voice Newsletter. 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.
All items in category Project Articles. In this article, Joel Hatch explains how to build a variable frequency synchronous motor controller to control turntable speed. In this article, Ron Tipton explores the use of stroboscope discs to determine whether your turntable is set to the correct rotational speed. 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 audkoxpress published in audioXpress from the author himself.
This article was originally published in audioXpress, April This article was originally published in audioXpress, March April 28, by Ari Polisois. The entire system runs on 8 AA batteries and should operate for approximately 4 hours continuously. Apart from looking at some commercially available stroboscope discs, Ron Tipton explains how ajdioxpress print one from files that audiozpress freely available on the Internet, and explains audioxpess to build your own multiple-LED lamp to check the rotations.
The square wave is auvioxpress into a small audio power op-amp. October 31, by George Ntanavaras. When it came to selecting topologies for the balanced inputs and outputs, I ruled out transformers due to high cost, physical bulk, and weight.
March 27, by Joel Hatch. The Mighty Mouse is indeed a good sounding and inexpensive project that is also a good introduction to tube amplification. 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. February 7, by Paul J. I completed the audioxpresss and construction of an archival auduoxpress 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.
Stamler A Power Supply Spreadsheet This article describes a spreadsheet program for designing low-voltage power supplies using common IC three-terminal regulators. A pot with 64 levels and precision metal film resistors that is hard to beat for sound or facility, as he describes it.
Charvat, two pre-amplifiers are used with a battery powered high voltage supply.
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.
This article was originally published in audioXpress, February The spreadsheets are in standard Excel format, and should audioxpresss in just about any spreadsheet program.
July 25, by Pete Millett. May 8, by Ari Polisois. There’s no better way to pay tribute to Ron than revisit some of these projects. The output of this op-amp is back-fed into the secondary of an audio auduoxpress transformer, generating high voltage AC V at 40 kHz. December 13, by Gregory L.
