7.4 Replacement of the Tube
1)
Ensure that the unit is isolated from its supply and, to avoidsevere burns, that the tube
that has to be replaced is no longer hot.
Ensure also that all terminals are at 0V, and if not use a shorting stick to remove any
residual charge.

Undo the fixing screws holding the tube access panel (22 Fig.1) to the front panel and
remove the access panel.

taking care not to damage them.
Re-mount the base on its pillars, without the tube.
