Integrated vacuum tube amplifier

A valve amplifier or tube amplifier is a type of electronic amplifier that uses vacuum tubes to increase the amplitude or power of a signal. Low to medium power valve amplifiers for frequencies below the microwaves were largely replaced by solid state amplifiers in the s and s. Valve amplifiers can be used for applications such as guitar amplifiers , satellite transponders such as DirecTV and GPS , high quality stereo amplifiers, military applications such as radar and very high power radio and UHF television transmitters. Until the invention of the transistor in , most practical high-frequency electronic amplifiers were made using thermionic valves.

This free guide discusses all relevant aspects for an integrated push-pull vacuum tube amplifier design, including the power supply unit.

To clarify the various concepts, I propose many practical examples using EL34, EL84, and 12AX7 vacuum tubes, to design the various parts of the circuits and to compute the values of the needed components.

Furthermore, the guide also contains a step by step design of an integrated push-pull vacuum tube amplifier, using EL84 power tubes, leveraging on all the notions introduced. If you prefer to immediately start reading the full text for free , you can directly jump to the summary of content. Elsewhere, please find below an overview of what is in the guide. First of all, after an introduction to the guide , the basic principles to understand vacuum tubes are discussed. Certainly, this is needed by the non-initiated.

However, If you already know what vacuum tubes are and how they operate, you can skip this part. Then, the guide discusses how vacuum tubes can be used as amplifiers. Most notably, here, you will learn the concepts of operating conditions, loadlines, biasing techniques, and amplifier classes. Continuing, the guide discusses how to design an integrated push-pull vacuum tube amplifier.

To do so, it starts from the single-ended configuration, then it introduces the push-pull configuration. Consequently, the various needed stages power, phase-split, and input stages , and global negative feedback are discussed in details. A significant part of the guide is also dedicated to the power supply unit design for a vacuum tube amplifier.

First, it introduces the rectifier configurations and filters to reduce voltage ripple, and to have a quiet amplifier. Then, it explains how to estimate the expected output DC voltage, ripple, and the current delivered. Furthermore, it also discusses how to design the power supplies for the fixed bias circuit and for the filaments of the vacuum tubes. Finally, the guide goes through a step by step design of an integrated push-pull amplifier with EL84 vacuum tubes in ultralinear configuration.

In this project, input and concertina stages, based on 12AX7 tubes, are directly coupled. First, the guide discusses the design of the power stage, the phase-split, and the input stage. Then, it discusses the design of the global negative feedback loop. Finally, it also provides the design of the corresponding power supply unit.

China vacuum tube amplifier


The MC 70th Anniversary Vacuum Tube Amplifier is a Watt per channel stereo amplifier and features a striking new design to celebrate our seven decades of handcrafting some of the best home audio equipment the world has ever heard. Utilizing our patented Unity Coupled Circuit output transformer technology — the same technology the company was founded on in — the full Watts can be delivered to almost any pair of speakers regardless if they have 2, 4 or 8 Ohm impedance. The stunning new design of the MC is highlighted by a bead blasted black anodized aluminum chassis accentuated with matte finish carbon fiber side panels. The front panel showcases a backlit laser cut McIntosh logo flanked by classic McIntosh knobs. The vacuum tubes are covered by a gauge stainless steel wire cage with a black powder coated finish. To the back are the two Unity Coupled Output Transformers with the power transformer centered between them. All three transformers are housed in glass topped extruded enclosures displaying the wiring diagram for each transformer. A 70th Anniversary badge is laser engraved into the top plate of the enclosures.

Audio Research VSi60 Integrated Tube Amplifier

For many, many years the SLI integrated amplifier has been the standard by which all other vacuum tube integrated amplifiers are judged…period! Thousands of music lovers all over the world have heard and seen the virtues of this spectacular vacuum tube integrated amplifier. Before we gloat about the sound of the SLI, just look at it. The open chassis showcasing the warm soft glow of the tubes only enhances its sonic beauty. It is a display piece for any setting, pure and simple. While only offering 15 watts per channel of pure class-A remote-controlled power, the CADSEI does things that almost no other amplifier today can achieve. Its careful attention to design and construction means that it is extremely quiet, allowing the tiniest musical details to float against a background of dead silence.

These are the best integrated amplifiers that we, the PTA team, have heard. It costs a little bit more but delivers a lot more in return—more power, an improved high-resolution DAC circuit and a nice remote control. One of the best integrated amplifiers for the money just got better. From the mind of the former designer for 47 Laboratories, the Sparkler Audio minimalist amp is borne from the same principles—simplicity, short signal paths and an impressively small list of internal parts.

Awesome stuff!!! The Esoteric F Integrated Amplifier deliversw into 8 ohms. Accuphase delivers an awesome integrated amplifier in the E! Accuphase delivers the E integrated amplifier as their introductory offering. Great piece at a very good price!

The realisation of a desirable ideal the ultimate refinement of separates in a single unit.

Together with Stereo Exchange. There seems to be a massive shortage of tube integrated amps in the market so we were thrilled to take this piece in. Not only is it a tube integrated, but it's made by one of our favorite companies right here in the USA, Audio Research. Their current offering will set you back the price of a modest new car. But this VSi60 from not all that long ago has most of the performance capabilities at a reasonable price. Best of all it arrived in pristine condition and includes the original manual and remote control. All of the tubes measured strong, controls are noise-free, and cosmetics are nearly perfect.

Ah, valves. How we like their delicacy, sonic warmth and the way they light up. There are still valve amplifier manufacturers that work tirelessly to emulate that rich sound of the valve amplifier era. PrimaLuna, Luxman and Cayin are designers and manufacturers of valve amplifiers that not only reproduce that classic valve sound but have made several improvements that enhance the sound quality and reliability of valves.
