• 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 six screws. You should now be able to access the underside
of the amplifier chassis. The preamp & output tubes are retained by spring
retainers which must be pulled away before the tubes 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 not attempt to service these
