1 Introduction 

 

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 
sensi

tivity” 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”. 

          IMPORTANT!
