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 switches on the front panel 

 

When re-packing please make sure the packaging does 
not foul the small switches. Normally the two hand cut-
outs are towards the rear of the amplifier. 
Do not ship with the valve cover as damage is likely to 
occur,  but  send  separately.  Do  not  return  valve  cover 
for service. 

 (Please keep this information for future use).
