OPERATING INSTRUCTIONS
To change a preamp tube:
Switch off the unit and unplug from the mains supply. Wait for the tubes to cool down.
The chassis needs to be removed from its wooden sleeve to allow changing of the preamp tubes, with reference to the diagram, this is easily
achieved by:
1. Removing the two side handles (5) by unscrewing the six No 8x1" (3) & four M5x30mm (2) on each handle. Remove the metal bar away from
the handle and then gently pull the plastic body out of its recess.
2. Remove the rear grill (8) by unscrewing the four 15mm screws (7) securing it in place.
3. Remove the four M6x30mm bolts (6) and finishing washers (4) from the front of the unit.

4. Finally remove the six M5x30mm screws (2) from the
base of the cabinet. You should now be able to slide the
amplifier forward freely. Be careful as the unit is very heavy.
The Pre-Amp tubes can now be removed by unclipping the
retaining clips and gently pulling them from their sockets. Take
care when fitting the replacment tubes and ensure that the
pins are all aligned properly. Refit the retaining clips.
The chassis is refitted by reversing the removal instructions.
