UNPACKING AND INSTALLATION
These amplifiers are shipped without the valves installed. It is
necessary to install the valves first. 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 does this for you.
Installing the valves
Please take care when unpacking the amplifiers as they are fairly heavy and
place on a suitable clean space (table or floor) it is recommend that you store
the packaging materials in case the unit requires shipping at a later date.
Carefully unwrap all the valves. You will find 1x 6SN7WGTA, 2 x 300B and 1x
5U4G valves for each amplifier.
Looking from the front of the amplifier, the first valve to insert is the 6SN7WGTA
valve which goes into the first valve base at the front of the amplifier.
Inspect the locating pin on the bottom center of the valve and align with the
valve base (the locating pin can only go in one way round due to a locating
spigot) and with gentle but firm pressure insert the valve. Please see diagram 1.
