UK  dealer  you  purchased  from  for  12  months 
from  the  date  of  purchase  for  parts  and  labour, 
excluding shipping. Valves are consumables and 
therefore on a 12 months pro-rata wear basis. 
Other  countries  may  vary,  ask  your  re-seller. 
Please  keep  your  receipt  as  proof  of  purchase, 
this will be needed.  

 
All units are individually tested for performance for at 
least six hours before despatch to you. In the unlikely 
event  that  you  believe  the  unit  is  not  functioning 
correctly,  it  may  be  helpful  to  contact  us  first  as  we 
may  be  able  to  assist  you.  Then  we  would  request 
that you return the item to us for further action.

Exclusions 

Claims for any  damage to  either amplifiers or valves 
must be reported within three days of receipt. 
 
This  amplifier  is  designed  for  normal  domestic  hi  fi 
use.  It  is  not  guaranteed  for  commercial,  Public 
Address  use,  or  use  in  other  situations.  The 
guarantee  becomes  void  if  the  unit  has  been 
modified in any way not approved by Icon Audio. 

 

10 Packing Instructions 

It  is  essential  that  the  original  custom  box  and 
packing  be  kept  for  shipping  as  this  provides 
vital  protection  during  transit.  Do  not  write  on 
box,  but  use  labels. 

Should  the  original  box  and 

packaging  be  lost  pack  very  carefully  in  alternative 
packaging. 

 

When returning units for service, do not send 
the valve cover, remote control or mains lead 
unless requested. 

 

Valves  MUST  be  removed,  numbered  and 
packed  in  “Bubblewrap”  or  similar  for 
protection  inside  the  valve  cover,  or  space 
where the valve cover would normally fit. 

 

Insert the piece of cardboard between the 
transformer  cover  and  the  valve  guard; 
this  will  prevent  transformer  damage  to 
paintwork during shipping.

 

 

Re-use  the  supplied  plastic  bag  to  keep  the 
amp clean and free from damp. 

 

If returning the valve cover, it is essential 
that adhesive tape be wrapped all the way 
over  valve  cover  and  underneath  the 
amplifier  to  prevent  the  valve  cover  from 
coming loose and causing damage. 

 

The  mains  lead  normally  fits  in  a  foam  cut-
out underneath the amplifier. 

 

If  the  amplifier  is  stored  in  the  box,  keep 
upright.
