Thank you for purchasing the Stereo 30se. This
unique design by David Shaw is the result of a
lifetime working with audio amplification. A great deal
of care has been taken in the design, selection of
components and production of this amplifier. With a
little care and attention the ST30se should give a
lifetime of pleasure.
The Stereo 30se is an integrated valve amplifier
capable of running in either pure triode mode (18w)
or Ultralinear mode (28w) which will give higher
power. Because the amplifier operates in CLASS A
the ST30 draws constant power at all times giving a
very smooth and warm sound.
The pre-amp is a high quality 'Passive' circuit using
silver audio cable and an ALPS volume control with
remote control. The ST30se is sensitive enough to be
used with virtually any modern source. A pre
amplifier may be used if desired using the "low
sensitivity" mode.
The circuit design is our own using only two stages
employing the venerable 6SN7 to giving an excellent
combination of the best of vintage valve sound, yet
accurate and dynamic to suit modern speakers and
recordings.

In order to get the best out of your amplifier,
please read the enclosed notes. Even if you are
experienced with valve amps please read the
'quick set up guide'. Should you be uncertain
about using your amplifier please contact us for
advice.
Valve (or Tube) amplifiers do the same job as a
solid state amplifier, but they do it differently. And
whilst solid state specifications look good on
paper even quite modest valve amplifiers can
have a richer, more textured sound. Our "old
school" method of point to point wiring hand wiring
without using printed circuit boards significantly
adds to the sound quality. Your ears may have
become accustomed to your old amplifier, so it
may take some hours before your ears attune
themselves to the new sound.
Your source, loudspeakers and room acoustics
will also affect the sound before it finally reaches
your ear. Some people find a small adjustment in
re positioning their speakers can help too. The
weakest link will always affect the listening quality.
When making judgements use a good well
balanced recording. Remember that a new
amplifier will take a few months to fully "burn in".
