Synopsis: This book moves beyond general principles of tube amplifier design to carry out an intense examination of one of the most famous circuits of the rock era. The book begins with the 5F6A's relatively simple triode preamps (bypassed cathode resistor, unbypassed cathode resistor, and cathode follower) and then progresses through the mathematically challenging tone stack, long-tailed-pair phase splitter, and push-pull power amp. Every formula for every tube is derived in all its gory detail. The author's methods include the classic load lines and composite characteristic curves of Frederick Terman and the Radiotron Designer's Handbook as well as more modern techniques like linear regression and the Discrete Fourier Transform. Special attention is paid to quantifying the push-pull amplifier's nonlinear response and to analyzing power supply voltage sag as it reacts over time. This expanded, second edition includes an enlarged, fold-out schematic of the Bassman and a new chapter on the Marshall JTM45, which is almost a direct copy of the 5F6-A. The Bassman 5F6A circuit has inspired guitar amplifier designs for over four decades, so sharpen your pencil, fire up your calculator, and find out what makes this amp rock!
From the Publisher: Why would a member of the IEEE Circuits and Systems Society, an organization dedicated to advancing the state of the art in electronics, write an entire book about the design of a vacuum tube amplifier manufactured more than four decades ago? Even back in 1959, the Bassman's innovation must have paled in comparison with the technological leaps being made by space-age transistor circuits.
To understand the motivation behind the book you need to understand what the tweed Bassman means to guitar players. To generations of professional musicians the Bassman's mix of harmonic overtones is the holy grail of tone, the perfect balance between clean reproduction and distortion-driven tonal ecstasy.
Its place in history is ironic, because the 5F6A wasn't even designed for the guitar - as its name implies it was intended to be a bass amplifier. Yet today more than ever the amp's sound hits the mark with guitar players the world over. More than forty years after the original 5F6A ceased production many of the best guitar amps, Marshalls in particular, are still based on its long-tailed-pair, negative feedback circuit design. It is to this lasting legacy that the book pays tribute.
The book has a 7-inch by 9-inch paperback format with a 1.7 mil laminated cover. It includes a bound, 18-inch by 9-inch Z-folded insert with the complete 5F6A schematic and the original manufacturer's voltage measurements.
