Thank you for purchasing the
20SE
. 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
experienced with hi fi Please read the 'quick set
up guide'. Should you be uncertain about
anything to do with your amplifier 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
judgements should be made with a 'clean' well
balanced recording.

The
Ultralinear stereo power amp. Using only one
output tube per channel. This makes for a very
simple design without the complexities of push-
pull operation. The biggest problem with single
ended designs is their low power and often poor
bass performance.
Developed over several years our primary goals
were: 1, To have enough power to drive modern
speakers to a good level. 2, Warm, yet detailed
sound without "soggy bass". 3, Not requiring a
large expensive power
expensive tube replacements. 4, Relatively simple
all triode drive stage for purest sound. 5, To use a
valve rectifier for extra smoothness. 6, Reliability
and simplicity of operation.
The excellent GEC
requirements with ease.
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 300mv or greater. Its simplicity coupled
with point to point hand wiring without the use of
printed circuit boards results in an open euphoric
sound that is wonderfully detailed and warm
sounding.
