The amplifiers are shipped without their valve compliment installed. It is necessary to
install the valves before operation.
It is essential that the valves are installed correctly or serious damage that is not
covered by the warranty will result. We recommend that your dealer perform
this procedure for you if you are in any way unsure.
FIRSTLY, ENSURE THAT THE AMPLIFIERS ARE NOT CONNECTED TO A MAINS
ELECTRICAL SUPPLY, AND THAT THE POWER CORDS ARE NOT CONNECTED
TO THE AMPLIFIER.
Remove the top covers from the amplifiers. There are a total of 20 screws used to
secure this cover on EACH chassis.
Now remove the valves that are packed separately and carefully unwrap them. Also
inspect the amplifiers to check that nothing has become damaged or dislodged
during transit.
In the above drawing, the positions of the valves are marked in
RED
