1 Introduction
Thank you for purchasing a
Stereo 40i
.
A great deal of care has been taken in the design,
selection of components and production of this
amplifier. We are sure that you will hear the
difference.
In order to get the best out of your amplifier,
please read the enclosed notes. Even if you are
not experienced with hi fi.
We would recommend
that everyone follow the ‘quick set up guide’.
Should you be uncertain about anything to do with
your
Stereo 40i
please contact us for
advice.
Hi fi reproduction is a long chain of events that
includes the recording, editing, mixing etc, before
being transferred to a medium such as LP, CD, or
FM, before being played through your own source
unit, the amplifier and finally loudspeakers.
Your room acoustics will also affect the sound
before it finally reaches your ear. Whilst the
amplifier is arguably the most important part of a
system, it is important to remember that the
weakest link will always affect the final results
when making judgements. And not all recordings
are ‘equal’! Therefore an amplifier which faithfully
reproduces the input signal will also reproduce
imperfections in the tonal balance and the
recording itself. Therefore setting up and
judgements should be made with a ‘clean’ well
balanced recording.
The
Stereo 40i
is a push-pull Ultralinear
stereo power amp, capable of running in either
pentode or triode mode, using the excellent EL34
valves and fixed bias mode. The driver and phase
splitting is all triode. The pre-amp is a high quality
‘Passive’ circuit using silver audio cable and an
ALPS ‘blue’ volume control. It is sensitive enough
to be used with all modern source equipment
having an output of 250mv or greater. Its
simplicity coupled with point to point wiring hand
wiring without the use of printed circuit boards
results in an open euphoric sound that is
wonderfully detailed and warm sounding.
This manual also covers the “
Special
Edition” & “ie”
models, where the tape
monitor, triode switch & silver Teflon
audio cable have been omitted.
