The most common triode type found in guitar amps is the ECC83 / 12AX7, while the ECC81 / 12AT7, ECC82 / 12AU7 and 12AY7 occasionally make an appearance. The consistent use of the same type of valves is partly historical, since many modern amplifiers are derivations (or merely copies!) of a few classic Fender amps. These options will improve the sound quality of your tube amplifier and still meet any budget. Let us provide our knowledge and experience to help you choose a vacuum tube package that will work great in your preamp and tube amp. If you do not find your amplifier listed we .
ICON AUDIO MP3 Price: £ From the highly respected UK outfit based in Leicester, this is one amp that most of the media has (criminally) ignored but is a great, small footprint (for the company, at any rate) valve-driven device that includes a headphone socket at the front with a neat, two-position, input selector and volume control. A vacuum tube, an electron tube, or valve (British usage) or, colloquially, a tube (North America), is a device that controls electric current flow in a high vacuum between electrodes to which an electric potential difference has been applied.. The type known as a thermionic tube or thermionic valve uses the phenomenon of thermionic emission of electrons from a hot cathode and is used for a.

In vacuum tubes used in power stages (for instance EL34 vacuum tubes), current ranges from 0 up to a few hundreds of milliamperes. With an appropriate configuration, this current variation can be exploited to obtain voltage and/or power amplifiers, where the voltage signal applied to the grid is .

Warning: the information in this book is about tube amplifiers in general but the author seems to have more experience with Hi-fi amps than guitar amps. The one guitar amp design the book discusses is an odd one that mixes the clean signal with the distorted signal in parallel rather than running the input through all the tubes in series/5().
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.
This book covers basic electronics related to vacuum tube amplifiers, an elementary guide for understanding and working with vacuum tube amplifier circuits. Sections cover electronic and audio information that are concise with many examples and illustrations.
Vacuum tube amplifying circuits are explained in simple terms without complicated math. This book is "A Training Course Text Prepared for Employees of the Long Lines Department American Telephone and Telegraph Company".
"Principles" is a bit of a misnomer - though this book does start out with fundamentals, it quickly dives off into AC circuits, vacuum tubes and amplifiers. Figure 9: Equivalent circuit of the voltage amplifier. The vacuum tube is seen as an AC voltage source equal to the amplification factor μ times the input signal V in, with opposite anode resistance and the load resistance are in series to the voltage source to form a voltage divider.

Vacuum tubes have long been known and favored for adding a very warm, rich, and identifiable musical element to the distortion of sound they produce, in contrast to the more artificial distortion of the more common transistor. Guitar Amp Books for Professional Builders Recently Published.

In electronics, a vacuum tube, electron tube (in North America), tube, or thermionic valve or valve (in British English) is a device controlling electric current through a vacuum in a sealed container.
The simplest vacuum tube, the diode, contains only two elements; current can only flow in one.

Vintage info from the days of vacuum tubes. Herein you will find a collection of vintage engineering texts, vacuum tube datasheets, and other obsolete information, presented free of charge and without annoying advertisements.
For other DIY-audio-related information, please visit Audiophiles swear by the quality of vacuum tube amplifiers, preferring their sound to semiconductor amps, and many professional musicians won’t consider using anything in their place.
Whether there’s any merit to this preference is a matter of some debate, but you can dive more into the fascinating world of tube sound in this thorough IEEE.
Example Choosing heaters transformers An EL34 vacuum tube requires V at A. If we need to provide electric power to the heaters of a stereo push-pull amplifier, composed of four EL34, with filaments connected in parallel, we need a step-down transformer of V, rated at least for 6A.
12AX7 tubes contains two vacuum tubes each requiring V at A.

Mullard Tube Circuits For Audio Amplifiers - Mullard Ltd. - ISBN The Mullard Tube Circuits For Audio Amplifiers book was first published in by Mullard, Britain's premier vacuum tube manufacturer. While this is an old book it is detailed and easy to follow. It is the source of the famed and Mullard amplifiers.
In power amplifiers built using vacuum tubes, as discussed later, generally the load consists of an output transformer, which adapts the impedance of the speaker to the load required by the vacuum tube.
In case of vacuum tubes used in input stages, as for instance 12AX7 vacuum tubes, given that the current variation from the anode to the. This inexpensive Tube Amplifier kit has been available for a number of years now and makes for a nice little tube amp.
