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.
