• To change a tube; switch off the unit and unplug from the
mains supply. Wait for the tubes to cool down. Lay amplifier
down on its front face and remove the protective grille held in
place with four screws. You should now be able to access the
underside of the amplifier chassis. The preamp tube is retained
by a screen can, turn this anti-clockwise & pull upwards away
from the tube. The tube can then be gently pulled out. The
output tube has a spring retainer which must be pulled away
before the Tube will come out, see photo opposite. (Removal
of both tubes can be eased by applying a slight rocking
motion as they are pulled, but ensure that it is only
slight, as the pins can easily be damaged).
Take care when pushing the new tubes
into place, make sure the pins are all
aligned properly and are located in
the valve base correctly before
fully fitting.
• Servicing: The user should
