Описание:
Volume 1 of the most complete and practical modern reference on tube guitar amplifiers
The first three chapters of this unique book cover introductory topics such as basic electronic circuits and passive components (resistors, capacitors, inductors), the building blocks of tube amplifiers. Audio amplifiers are also investigated as "black boxes", from the outside perspective, and important concepts such as spectra, gain, bandwidth and distortion are introduced.
Chapters four to six explain operational principles behind vacuum tubes (diodes, triodes, tetrodes and pentodes), and their use as rectifiers and active amplification components in guitar amps.
The rest of the book progresses through various stages of guitar amps, from input circuits and preamplifier stages, through tone control circuits and analog effects, to output or power stages.
After the in-depth coverage of tube power supplies, single-ended output stages (triode, pentode and "ultralinear") are covered first, followed by phase inverters and push-pull circuits.
Various types of negative feedback are explained, together with their benefits and drawbacks. The associated controls such as "Presence", "Resonance" and "Texture(TM)" are also discussed, using Peavey ValveKing 212 amp as a case study.
Despite claims by their manufacturers, many modern guitar amps aren't "all tube" at all, but hybrid designs. Most have a single tube in preamp stages to "color" the sound, and a cheap solid state output stage (usually using integrated circuits). Others take the opposite approach, choosing semiconductor preamp stages and a tubed power stage. For that reason solid state (semiconductor) components and amplifiers are covered here briefly, together with two examples of hybrid amps.
This practical DIY manual is richly and professionally illustrated with photographs of tubes, components and amplifiers, circuit diagrams, tube pinouts, curves and loadlines, graphs and charts. These valuable illustrations make it faster and easier to comprehend issues, a picture is truly worth a thousand words! All the information required to design and build tube guitar amplifiers is compiled in one place.

Описание: When Kelly Newton decided at the last minute to join her friends for a two-week getaway, all she expected was time away from the stress of her job, a hot tub, and hiking trails by the water. She didn't count on her powerful attraction to Josie Harlow, the charismatic and totally unavailable owner of the lesbian resort in the upper peninsula of Michigan. Josie Harlow knows from past experience that happily ever after is a fairy tale. When she meets Kelly, her desire is instantaneous, but a beautiful distraction is the last thing she needs as she works to make the resort a success, withstand the pressure to sell her land, and hunt down the hooligans damaging her property. When her grandmother is no longer able to care for herself, Josie has to figure out how to support her elder and deal with her growing feelings for Kelly too. Can a romantic looking for a long-term, committed relationship and a jaded cynic too busy for love conquer life's struggles and find their way to what matters most?

How to Use, Calibrate, Repair and Upgrade Vacuum Tube Testers
The revival of tube technology in guitar and audiophile amplifiers has also led to the renewed interest in vacuum tube testers and their ultimate purpose, testing and matching of audio tubes. The prices of vintage tube testers have risen to levels unimaginable just a few years earlier. Tube testers their owners could not give away then are now fetching many hundreds and some even thousands of dollars.
Due to high prices of both NOS and currently produced tubes, audiophiles and guitar players want to test & match their own tubes to make sure they've got what the sellers promised, and to see if their old tubes needed replacing in the first place.
If you are a technician who fixes amps or tube seller, then a reliable and accurate tube tester will be beneficial to your business and will improve your bottom line. Declared results of meaningful tests will help you get a higher price for your tubes and repair or tube matching services.
Tube testers and tube testing are so misunderstood that buying a wrong tube tester, using it to do things it was never designed to do, damaging or even destroying tubes it was supposed to test, are just some of the consequences of such ignorance, myths and misconceptions.
Tube testers suffer from false positives and false negatives. A false positive is when a perfectly good tube is tested as "faulty", "worn" or "marginal" and discarded. The false negative is when a faulty tube is passed by a tube tester as a healthy one, and, as a result, an expensive repair is likely if a faulty tube causes secondary faults in the actual equipment such as tube amplifier.
Just like cars, some tube testers look good but aren't that easy or pleasurable to use, others look old fashioned or complicated, but are quite accurate and capable. Some brands and models are overpriced, others are under-appreciated and thus cheaper than they should be.
One aim of this unique book is to identify strengths and weaknesses of various types or families of tube testers in a general sense, and positive and negative aspects of many specific models that often come up for sale.
Design, functionality, calibration and modifications of testers by B&K, Hickok, Triplett, Mercury, Sencore, Weston, Simpson, AVO, Taylor, RCA, Precise, Precision, Eico, Jackson, Sylvania, Knight, Heathkit, Seco, Sico, Conar, Metrix and other brands are discussed.
This practical technical manual is richly illustrated with photographs of inside and outside views of tube testers, their circuit diagrams and various graphs and charts.
Who is this book for?

The only practical audio transformer design & construction manual in English language
The design of chokes, small power transformers (those used in tube amplifiers and preamplifiers) and audio (output and interstage) transformers is such a specialist topic that even most electronics engineers would not even know how and where to start, let alone produce a finished, working transformer.
Commercial transformers and chokes are available, but most are very expensive, and those that are reasonably priced usually aren't of best quality. Plus, since they are such heavy and bulky components, international postage or courier costs are significant.
The physical principles behind transformer operation are quite complex and mathematical modeling of transformers require strong mathematical skills, deterring amateurs and DIY enthusiasts from studying the subject. While some basic understanding of operational principles is necessary, luckily, transformer design can be greatly simplified by using a few basic rules-of-thumb formulas.
Likewise, once you have a finished design (a detailed winding diagram), transformer winding & assembly is surprisingly easy. Apart from the materials (such as bobbins, laminations, insulation and magnet wire), all you need is a simple winding machine (can be of DIY variety), good hand-eye coordination and patience.
Your DIY transformers will almost always be significantly cheaper than commercial alternatives and often of better quality and better sounding than famous names transformers costing many hundreds and even thousands of dollars each.
There are more than 40 ( ) detailed designs of various power, output & interstage transformers and filtering, grid & anode chokes in this unique manual. Even if you don't feel like investing time and effort into mastering the art of transformer making, simply take those winding diagrams to any transformer making shop and have your transformers professionally made for a fraction of the price of commercial alternatives.
This practical design & construction manual is richly and professionally illustrated with photographs of transformers, circuit diagrams, winding diagrams, reference tables, graphs and charts. These valuable illustrations make it faster and easier to comprehend issues and concepts. A picture is truly worth a thousand words. Indeed, all the information required to design, wind and test chokes, power and audio transformers is within these covers.

Описание: High Quality Content by WIKIPEDIA articles! Motorpsycho (initiated 1989 at Trondertun, Melhus, Norway) is a band from Trondheim. Their music can generally be defined as psychedelic rock, but they also mix in elements from metal, jazz, post-rock, pop and many other musical styles. The members of the band are Bent Saether (born February 18, 1969, bass/vocals), Hans Magnus "Snah" Ryan (born December 31, 1969, guitar/vocals) and Kenneth Kapstad (born April 20, 1979 drums). Until March 2005, Hakon Gebhardt (born June 21, 1969, drums) was also an integral part of the band. A press release concerning his departure is published at the Unofficial Website. In December 2007 it was announced that former Gate drummer Kenneth Kapstad was the new drummer in the band as well as an official band member.
