We do not make coils wound on plastic bobbins due to risk of microphony, nor do we use ferrite cored coils that saturate abruptly. All Jantzen coils. audioXpress 1. Horn Theory: An Introduction, Part 1. By Bjørn Kolbrek. This author presents a two-part introduction to horns—their definition, features.
Dell deserves a big slap on the back, a free beer, and your subscription. This article from respected author Ari Polisois deals with a single-ended amplifier with enough power to drive even the most difficult speaker xudioxpress — delivering 50W per channel. This article was originally published in audioXpress, February So is the above amplifier an OTL? Kit includes 4 bulbs and 4 new filter caps they are GM factory color. Well, now that I am stirred up, I might as well go into full rant mode.
In fact, I wish to make a request of my fellow TCJers: Read this reference article, originally published in audioXpress, September Let’s read what the good folks at Bur-Brown have to say about their INA differential line receiver: February 7, by Paul J. It took many engineers to design that CD player and it takes many engineers to understand it.
The spreadsheets are in standard Excel format, and should work in just about any spreadsheet program. One test we could perform is to remove the INA differential line receiver and measure the voltage audiopxress into the loudspeaker while the PL is driven to full output.

If the tube mixes heater hum into its output, the solid-state amplifier will faithfully reproduce the hum at the loudspeakers terminals. Providing the highest level of quality for recording, mixing and mastering tasks, as well as for music production in a single environment, the new Samplitude Pro X4 expands on its most praised features, now adding Automation Lanes for optimal control and overview of track automation data, a new plug-in browser for quick searches for effects and instruments, new MIDI editing functions and improved MIDI workflow.
So, how did it sound? In audooxpress nod to the Maker Movement, this project uses a common open-source microcontroller module, ahdioxpress Arduino, to build an automatic power controller for a tube power amplifier. Not too long ago, 50 years ago let’s say, the average audiophile reigned over his system, owning an understanding of the circuitry and the mechanics involved, building and designing audioxpresss of it himself, selecting and choosing the fundamentals, triode or pentode, single-ended or push-pull, rather than just choosing the appearances: Thus, it seems ausioxpress Mr.
April 19, by Paul Loewenstein. All items tagged with audioXpress archive Circlotron Lie Detector With the likely 2080 of a new Clinton presidency, what the world needs is a good tube-based lie detector. January 29, by audioXpress Staff. Yes there have been a few weak articles, but there have also been many, many great articles.
Getting the Most from THAT’s Balanced Line Drivers and Receivers
If the tube does not act on an input signal, the solid-state power amplifier remains oblivious to the signal. Okay, now brace yourself audioxpresss examining the schematic below; it is not nearly as complicated as it seems at first glance. If you wish to build Mr van Doorn’s amplifier, please do and I wish you the best of luck.
The poor rich kid, hobbled by too much money and ahdioxpress a fear of grease under his fingernails, can only hope to buy, but never really own such a hotrod. In over 30 years of designing loudspeakers, I have found the following measurements taken as a group provide the strongest predictor of loudspeaker preference available to us today.
In fact, this is the highest quality kit I’ve seen anywhere, of anything. Well, let us engage in some more topology alteration. I’m sure you could charge double and still have happy customers. 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.
Now let us add the tube input stage back into the OTL amplifier there is not much point to having an OTL amplifier without tubes and let us look at where the tube’s current flows.
October 3, by Ward Maas. InaudioXpress invited Scott Dorsey to update his popular reamping project that modeled audiopxress source impedances of a couple typical guitar pickups. Lately they have kindly printed projects that I had already posted on the web, but I decided that they deserve a little better than that. Medias this blog was made to help people to easily download or read PDF files. The project started with a clean sheet, looking to address potentiometer design with a quality that rivaled auduoxpress designs while maintaining a reasonable cost.

Still, this seems a petty quibble when we are offered aydioxpress high-wattage, affordable, hybrid, OTL power amplifier. The PB shares an almost identical feature set with the existing PB.

I have described Aikido frontends driving gainclones beforebut I would prefer a simpler solution, such as the following circuit, which I have shown before.
