BOOK CODE 2005
The first notable contribution of Milliard design engineers to the
specialist world of high-quality sound reproduction was the now-
famous 'Five-Ten' amplifier circuit which was introduced in the
summer of 1954. In subsequent years, a succession of designs for
high-quality circuits has issued from the Mullard Applications
Research Laboratory, and these designs include circuits for
power amplifiers and pre-amplifiers, circuits suitable for tape-
recording equipment and, most recently of all, circuits for
Many of these circuits have been described in articles in
various magazines or have appeared in the form of booklets or
leaflets. The others have only recently been released by the
laboratory, and have not yet been published. The object of this
book is to present the most up-to-date versions of the published
circuits together with the new stereophonic circuits in a way
which will be useful and convenient to equipment manu-
facturers, service engineers and home constructors. A list is given
on page vi of the earlier Mullard publications which have been
incorporated in this book. These publications may be useful for
purposes of comparison, but it should be appreciated that the
information given here is the latest available and consequently,
supersedes that issued elsewhere.
Most of the material contained in this book is based on work
undertaken at the Mullard Applications Research Laboratory.
The largest contributions have been made by R. S. Babbs, D. H.
W. Busby, P. S. Dallosso, C. Hardcastle, J. C. Latham and the
late W. A. Ferguson.
While the circuits described in this book have been designed
by Mullard engineers, it should be noted that Mullard Limited
do not manufacture or market equipment or kits of equipment
based on the circuits. Mullard Limited will not consent to the use
of the 'Mullard' trademark in relation to equipment based on the
circuits described, but will not object to appropriate references to
Mullard circuits, specifications or designs. Also, the information
contained in this book does not imply any authority or license for
the utilization of any patented feature.
