Cary Audio SLI-80 Integrated Tube Amplifer (Black)
For many years the SLI-80 integrated amplifier has represented Cary Audio's least expensive entry into the magic of tube music systems. Thousands of satisfied music lovers have used the SLI-80 with all types of other equipment, and just continue to use it after the rest of their systems change. It features three pairs of RCA single-ended inputs, a pair of preamplifier outputs to use it for biamping or adding a powered subwoofer, a switchable headphone amplifier, and a remote control to adjust volume or mute the sound. The amplifier section of the SLI-80 has a feature allowing you to decide how to configure the tubes on the fly, depending on your musical tastes of the moment, your speakers, and how loudly you want to listen. A pair of toggle switches will select either triode mode producing 40 watts per channel of pure class-A power, or ultra linear mode which doubles power to 80 watts per channel in class-AB. If you're listening to more subtle music and want to hear all of the inner detail, select triode mode for the most lifelike imaging and tonal accuracy. If you want to really let loose, switch to ultra linear mode and enjoy the extra power and dynamics. Your choice!

Vacuum Tube Amplifier Basics
It is true that accurately calculating electronic circuits can involve complicated formulas, but for the electronic hobbyist it is not necessary to perform at the level of an electrical engineer. With some basic knowledge it is possible for the hobbyist to design and build vacuum tube audio amplifiers that perform well. This book covers basic electronics related to vacuum tube amplifiers, an elementary reference guide for the novice working with vacuum tube amplifier circuits. Written in sections that are concise, many with examples and illustrations. Sections help you read at your own pace, convenient to stop after a section, skip around sections or refer back to a section. For the novice not versed in electronics, electronic principles are included along with several sections covering electronic and audio basics. Vacuum tube amplifying circuits are explained in simple terms without complicated math. Math is primarily basic math and a few simple formulas all solvable with a standard calculator and presented with examples. Principles of vacuum tube operation includes function of grids, effect of tube capacitance, tube resistance and heat dissipation. Power supply sections cover vacuum tube and solid state rectifier conversion of AC to DC and DC filtering. A sample power supply is used to explain calculating loads, determining required transformer ratings and component values. How to calculate a primary fuse value is also explained. Includes bias, bias supplies, calculating voltage gain and more. A table of component values for the popular 12AX7 in various operating parameters simplifies amplifier stage design. Includes project circuits with parts list and component layouts for a Buffer Line Amplifier with 25db gain, Triode Balanced-Unbalanced Input, Tone Control Stage, Turntable Pre-Amplifier, 6V6SE Stereo Amplifier, 6V6SE Monoblock Amplifier and a 30 Watt Monoblock Amplifier designed for tube rolling using various type output tubes. Also, included is a Guitar Amplifier project.
Tubes and Circuits
The most up to date vacuum tube design book currently available. Packed with information...Loaded with projects...Nothing like it anywhere! Join Transcendent Sound’s Bruce Rozenblit as he takes you on a journey from the basics of tube circuitry, through advanced designs. Tubes and Circuits is a condensed engineering manual that teaches the theory and operation of vacuum tubes—as well as circuit design. In addition, five projects are included that you can build. Projects provide step-by-step design procedures, equations, schematics, parts lists, and photos to assist the hobbyist in construction. Build a state of the art, very low cost, 15W OTL (output transformerless) amplifier. Complete plans for a 300B OTL. Own most glorious 1 watt in all of audio. Pure single-ended, Class A sonic heaven. (See website for updates, www.transendentsound.com) A tube tester that tests virtually all current production audio and guitar amp tubes—can be user modified to test any tube; a simple device used for testing most octal based rectifier tubes and a tube analyzer used for manually determining tube constants and bias currents. Tubes and Circuits provides all design procedures and equations necessary to allow readers to create their own designs. Practical methods are revealed—all built upon a solid theoretical base. Bruce Rozenblit shares his decades of experience designing hi-end tube audio equipment. Nothing has been held back. Topics include the essential physics required to understand circuits. Explains in detail what electricity is and how it works. Shows how DC current flows and behaves through resistive elements. Detailed information on AC circuit theory, reactive elements, and how they affect signals. What inductance is and how it is created. How components are used to create networks and interact with each other— includes transformer theory. Shows how feedback works and how best to use it. Reveals in detail the chemical and physical processes of how vacuum tubes function, generate current, age, and deteriorate. Shows how the electric fields inside vacuum tubes cause them to work. Demonstrates what tube constants are and how to use them. Shows how to use tube characteristic charts to derive the tube constants used in design equations. Explains load lines and their application. Detailed operation and all design equations for virtually all of the tube circuits used in high-end audio. Includes single-ended and push-pull transformer coupled output stages. Basic information on power supply design and function. All of the theory is put to use and made practical in the project chapters. Learn how to design OTL amplifiers. Anyone that uses vacuum tubes, from the hobbyist, the musician, to the design professional, would benefit from Tubes and Circuits.
