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.
2)
Undo the fixing screws holding the tube access panel (17 Fig.1) to the front panel and
remove the access panel.
3)
Remove the tube from its supporting socket, pulling in a direction perpendicular to its
socket.
4)
Should the tube prove excessively difficult to extract, unscrew the four screws holding
the base of the anode contacts to the 4 teflon pillars.
Once the tube has been extracted from its socket, attempt to remove the anode contacts
taking care not to damage them.
Re-mount the base on its pillars, without the tube.
5)
To fit the new tube, follow the procedure from step 2 to step 5 in paragraph 3.3
