Congratulations on your decision to become the owner of the AudioValve BALDUR 70
class-A triode power amplifier. This manual has been prepared to help you understand
the operation of your amplifier and to provide some information about its design and the
variety of ways in which it may be used.
PART 1 – OVERVIEW
1. Introduction to AudioValve
All AudioValve products are designed by Helmut Becker and feature advanced, modern
circuitry, combined with the warm sweet sound of valves. Now it is no longer
necessary to sacrifice one to get the other. Combining the finest in modern valve
technology with sophisticated smart- bias circuitry, AudioValve brings you the best of
both worlds - and more.
With contemporarily-styled chassis built from 4 & 5 mm laser-cut steel, every amplifier
and pre-amplifier we manufacture utilises double sided PC boards and automatic bias
regulators to ensure a continuously uniform current flow to and a perfect match between
all the valves throughout their entire life, even as the various valves decay at different
rates.
Unlike other valve amplifiers, where a certain amount of guesswork and experience
is required to know when valves need to be replaced, with AudioValve amplifiers
not only do valves not have to be removed prematurely (prior to burn out), but when
burnt out does occur, only the bad valves need to be replaced. The amplifier will
automatically adjust and distribute the total current flow to optimally match the new
configuration.
AudioValve amplifiers always deliver nothing but the most advanced, economical, high
quality valve sound. Power output valves in most models may be varied among several
different types with no modifications to the units, so that an appreciable degree of sonic
system matching and user preference may be accommodated. No matter what
combination of valves one uses (differing valves, new valves, old valves), one will
experience at all times the balanced and coherent sound of amplifiers working with brand
new, perfectly matched valves. The bonus is that there is never any need to use a meter
or screwdriver to adjust bias on any valve in any condition of operation. AudioValve’s
smart - bias circuitry is the best and most unobtrusive available!
The BALDUR 70 power amplifier represents exceptional value for money. We have
designed and manufactured this power amplifier to faithfully and accurately reproduce
music. The high quality of components used and advanced valve operational principles
employed in this design ensures that you will enjoy the superb audio performance
and pride of ownership, inherent in such a hand-crafted product as this, for many years
to come.
