Book excerpt: A project book for the advanced builder, includes circuit diagrams and circuit descriptions to build a gain controlled amplifier also referred to as a compressor. This type of amplifier is used to prevent over-driving audio systems by maintaining an average output and keep levels in a more comfortable listening range. This particular design uses all triode vacuum tubes including a triode gain control stage, all stages are built around the popular 12AX7 tube. Triodes are used because they produce primarily second harmonic content when harmonic distortion occurs, the addition of low-level second harmonics enhances the sound. The design uses a variable compression ratio, the ratio becomes tighter as the input level increases past the compression threshold. This allows soft passages to retain high dynamics while imposing more control on loud passages. The amplifier uses broadband compression to maintain the original sound balance. A slow gain control is used as an average level reference on which a faster gain control rides, ratio between the two is adjustable. Gain control is non-intrusive and dynamics are maintained, this is not a brick wall processor. Useful gain control is a 30DB range.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book excerpt: 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.
