DISASSEMBLY
1. At the XLR-3 end of the preamplifier, turn the
slotted-head setscrew fully inward (counterclock-
wise), and use a long-nose pliers to withdraw the
connector from the case.
2. Unsolder the three lead wires from the XLR-3 board.
3. Remove all four Phillips-head screws from the ILP-1
case (three on the switch side, one on the back).
4. Grasp the end cap and withdraw the cap assembly,
pc board assembly, and connecting wires and jacks
from the case.
REASSEMBLY
1. Make sure the pc board is seated in the slot of the
end cap and that no wires are pinched.
2. With the XLR-3 connecting wires foremost, feed the
end-cap-board assembly into the case. Take care
not to pinch the wires connecting the board to the
end cap.
3. Rotate the assembly until the four holes for the Phil-
lips screws line up with the holes in the case.
4. Re-install the four Phillips screws.
5. Resolder the three lead wires to the back of the
XLR-3 board as shown in Figure 2.

6. Replace the XLR-3 board-connector assembly in the
case, lining up the key in the connector with the slot
in the case. Take care not to engage the butterfly-
shaped ground contact in the key slot, as this pre-
vents the connector from seating properly.
7. Insert the connector into the case until the slotted
setscrew can be seen through the case hole; then
tighten the setscrew by turning it clockwise.
