Caution: This amplifier is very heavy! 

 

Lift  the  amplifier  out  of  its  packing  by 
using  the  two  “hand  cut-outs”  in  the 
bottom packing near the transformers. 

 

Or you may find it easier to remove the 
unit using the following procedure: 

 

1.  With  the  top  packing  in  place,  turn 

the box “upside down” with the “flaps” 
open. 

2.  Lift the cardboard box off. 
3.  Remove the bottom packing first. 
4.  Turn  the  unit  the  right  way  up  and 

remove the top packing. 

 

Please be careful not to damage the 
small  “tape  monitor”  and  “triode” 
switches on the front panel 

 

When  re-packing  ensure  small  switches  do  not  foul 
packaging, the two hand cut-outs are normally towards 
the rear of the amplifier. 
Do not ship with the valve cover as damage is likely to 
occur,  unless  you  have  the  original  packing.  Or  send 
separately. Do not return valve cover for service. 

 (Please keep this information for future use).
