3.2.9 Removing the mains transformer
— Remove wrap-around cover and rear panel (section 3.2.2)
— Take the lid off the voltage adapter compartment after removing the 4cross-slotted screws
— Remove the 4cross-slotted screws that hold the lid of the transformer compartment
— Lift the lid with the attached transformer, simultaneously sliding the wire form between transformer and
voltage adapter out of the slit in the transformer compartment
— The transformer and thermal fuse are then accessible for replacement
3.2.10 Replacing the thermal fuse
— Remove the mains transformer (section 3.2.9)
— Unsolder fuse terminals 1 and 2 (Fig. 3.11)
— Only the fuse wire of the old fuse is replaced and not the complete fuse; to this end, bend the housing of
the fuse slightly outwards, disengage the locking pin and pull out the wire
— Take the new fuse and remove the fuse wire out of its housing in the same way as described above
— Push the new fuse wire into the housing of the old one until the locking pin snaps into the hole. The loop in
the fuse wire must point to terminal 1
— Solder the fuse wire to terminals 1 and 2
3.2.11 Replacing the delay line unit
— If there is a defect in the delay line, the complete delay line unit must be replaced.
— Replacement is self-evident, but take care not to interchange the connections at the same end of the delay
line; interchange the connections when rotating the POSITION control clockwise, results in a downward
movement of the trace.
