Vacuum tube fundamental circuit design written for the novice interested in vacuum tube amplifier construction. A brief concise book covering several factors of circuit design including bias requirements, voltage gain requirements and power supply requirements.To help understand circuit operation rather than use traditional schematic drawings pictorial illustrations are used. In several sections circuit operation is demonstrated using illustrations along with a vacuum tube breadboard. Experiments are used to correlate circuit design to actual working circuits.Circuit calculations involving fundamental electronic formulas can be performed using a standard twelve digit calculator. Examples of how to solve calculations are provided. Basic electronic knowledge of voltage, current and ohms law related to vacuum tube circuit design is included where appropriate.The 70+ pages of circuit design contain enough information to design high quality vacuum tube amplifier circuits. The last few pages of the book have related information including how to use sound pressure levels to determine amplifier power required to produce desired loudness.

"Written for electronic engineers and professional amp builders, Guitar Amplifier Preamps moves beyond simplistic advice and cookbook solutions to present a complete guide to the theory and operation of triode and pentode voltage amplification"--P. 4 of cover.

"The most comprehensive and up to date text on vacuum tube audio currently available"--Page 4 of cover.

Discover (or rediscover) the fun and magic of building electronic circuits with thermatrons (vacuum tubes). This book has everything you need to know about the art and science of thermatron design and construction. It pulls together, in one easy to read book, thermatron types and characteristics, thermatron homebrew techniques, and how to design audio and RF triode and pentode circuits. The book is written primarily for radio amateurs (or audio equipment builders) that already understands basic electronics but have forgotten or never had the pleasure of working with hollow-state devices. The Second Edition includes over 50+ pages of new and revised material including a new chapter on thermatron oscillator design.

THE TUBE AMP BOOK WITH AUDIO ONLINE ERRATA SHEET ADDED.

This book is written for electronic hobbyist interested in working with vacuum tube circuits. A wide range of reference material related to vacuum tubes and audio are concise with examples and illustrations.Principles of vacuum tube operation includes function of grids, effect of tube capacitance, tube resistance, heat dissipation and voltage gain. A table of component values for the popular 12AX7 in various operating parameters simplifies amplifier stage design. 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. Includes high voltage, bias and filament supplies.For the novice not versed in electronics several sections cover electronic basics. Includes how capacitors work, voltage, current, ohms law and reading circuit drawings.Working with electronics and vacuum tube circuits requires some math. Circuit calculations in this book use various forms of addition, subtraction, multiplication and division. Formulas are all solvable using a standard 12 digit calculator. Calculations are presented with examples.The last part of the book has amplifier project circuits with parts list and component layout drawings. Projects include a line amplifier with 25db gain, triode balanced-unbalanced input stage, tone control stage, turntable pre-amplifier, 6V6SE Class A stereo amplifier, 6V6SE Class A monoblock amplifier, 30 watt monoblock amplifier and a 5 watt guitar amplifier with adjustable overdrive. The 30 watt monoblock amplifier is designed for tube rolling using various type output tubes.Current version of book was updated in April of 2017.
