8, Replacing the small 12AT7/12AX7 valves: 

 

The outer pair are 12AT7/ECC81, the inner pair are 
12AX7/ECC83 these are phase splitter double triodes. 
No set up is required. Care should be taken when 
removing and inserting not to bend the pins. If this 
happens gently bend the pins back into shape. (These 

valves are similar with the same pin connection; 
accidental wrong insertion would not cause damage). 

 

Icon Audio are happy to check the valves or amp & 
your re-bias your amp free of charge.

9 Packing Instructions 

It is essential that the original box and packing be 
kept in good condition, as this provides vital 
protection during transit. Please do not write on 
box, but use removable labels. 

Should the original 

box and packaging be lost or become unusable a 
repacking charge of one hundred pounds will be 
made. If you have any doubts about this please 
contact us. 

  Re-use the supplied plastic bag to keep the 

amp clean and free from damp. 

  The mains lead fits in a foam cut-out 

underneath the amplifier. 

 

Insert the piece of cardboard or pieces of 
foam between the transformer cover and 
the valve guard; this will prevent the valve 
cover damaging the transformer 
paintwork. 

  Remove the valves and pack in original 

boxes and packing. 

  If stored in the box, keep upright.
