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. the associated controls such as "presence", "resonance" and "texture" are also discussed, using peavey valve – king 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. – who is this book for? -guitar players wanting to learn how tubes and tube amplifiers work.- diy constructors who want to build, service or modify tube guitar amps.- buyers and sellers of tube guitar amps who need a better understanding of tube technology.- electronic technicians and engineers familiar with solid state devices and amps, who want to expand their knowledge of tubes and their circuits.- anyone who wants to learn how to design, build, test, fix, or upgrade tube guitar amps.

Tung sol 5751 dual triode preamp tube made in russia nos specs call the 5751 a “special 12ax7” having a high-mu amplification factor of 70. tung sol 5751 dual triode preamp tube. made in russia. nos specs call the 5751 a “special 12ax7” having a high-mu amplification factor of 70.

It is a premium quality 12au7 tube built to match the performance of the military/industrial original ge 6189 tube. this tube performs well as a preamp tube or driver tube. the 12au7 tube type is equivalent to the european ecc82 tube and can be used in any 12au7 or ecc82 circuit. the tung-sol name and trademark have been acquired by the new sensor corporation. this new production tungsol tube is manufactured at their xpo-pul factory (also known as reflektor) in saratov, russia. new sensor is an american corporation and since taking ownership of this factory has been steadily improving the quality of current production tubes.

Built to the same special tube request specs of leading amp manufacturers of the 1960s, tungsol 6l6 gc str power tubes are rugged and reliable power tubes that excel in the most demanding guitar amp circuits. choose from soft, medium, or hard in the drop down menu to get the right tube for your needs. soft, medium, and hard style descriptions refer to break up modes of the tube for an overdriven guitar signal.soft tubes have lower plate current and transductance matching numbers and reach saturation and break-up quicker. they are perfect for blues guitarists for the because of the tonal break-up and sustain they give you. hard tubes on the other hand have a much higher amount of clean headroom before they give you that break-up and distortion. with a high plate current and transconductance matching numbers, they take longer to reach full saturation and are the preferred tubes for those into jazz, country, or bass, and guitarists who use various effects pedals for creating distortion. medium tubes, as you'd think, fall in between these two, as far as break-up, headroom, saturation, etc. and are a more versatile option if you play a little bit of everything.
