a magazine review of the TUT series
There are certain tones anyone can recognize.
The
idea of "iconic" sounds and circuits is the basis for this
book's investigation of how these tones are created, how
we can create new ones, and how we improve upon age-old
circuit methods.
The
issues of circuit compromise and historical relevance for
each design are explored, with an eye - or ear? - to improving
signal-to-noise ratios and reliability. Some can be improved
through simple re-arrangements of wiring, while others require
greater overhaul. Grounding and wiring are detailed, with
proper methods and correct physical interconnection of components
highlighted.
Iconic
circuits are reviewed, beginning with how the original examples
were wired, how that wiring can be improved, what compromises
were made and why, how to correct those compromises, and
further improvements we can incorporate. We also explore
the compromises we introduce if we want to build the same
circuit in a number of physically different styles. You
can build a Champ, Bassman or SVT any way you wish, but
what are the ramifications? You will know once you read
through TUT3.
Both
bass and guitar systems are presented, as there are iconic
sounds for each instrument. If you always wanted to build
your very own SVT but couldn't find the transformers or
wiring diagrams, TUT3 will show you an "easy
SVT" and an easier Portaflex tribute. Two different
Bassman icons are illustrated along with the variations
of that brand's design. Neat tricks to improve the Marshall
800 master-volume amp are shown, and also a way to build
an AC-30 that does not "eat" tubes. How about
a Hiwatt Bulldog project that Pete Townshend could smash
an axe over?
This
is a construction-oriented book including both schematic
and layout drawings for each icon. You wouldn't expect twenty-six
variations of the simple Champ, but they are all here. Modern
fashion is melded seamlessly with vintage groove so you
can build the amp you really want, or modify an existing
amp to your own needs. Practical guidance is given for the
order of construction, incremental testing, wiring techniques,
easy bias circuits and bias access considerations. Eighteen
chapters cover it all with clear wiring diagrams so you
can build an amp right from the book.
Amp
construction made easy!
