Mullard Circuits for Audio Amplifiers
Encyclopedia
"Mullard Circuits for Audio Amplifiers" is a famous book by the Technical Services Department of Mullard
Ltd, a British
valve
manufacturing company. First published in 1959 and then reprinted several times it contained a number of designs by Mullard engineers for high quality audio amplifiers, which were to be used by amateur
constructors as well as by manufacturers as the basis for many products that formed part of the High Fidelity
audio movement in Britain in the 1960s.
Particularly iconic designs were the Mullard 5-10
and the Mullard 5-20, ten and twenty watt
power amplifiers. Circuits for preamplifiers with tone controls and tape recorder amplifiers were also included, along with information regarding record and tape equalisation standards.
