DISASSEMBLY/ASSEMBLY PROCEDURES
6.2
Carefully line up the holes of the
regulator board with the nylon standoffs
mounted on the power supply board.
Snap three corners of the board onto each
nylon standoff.
6.3
Replace the transformer (4) using
procedure 12. Refer to Figures 7 and16 for
correct wire locations.
6.4
Connect the cables from the line cord
(31) (for 240V, line cord and ground) to the
line filters terminals (10).
6.5
Connect the cables to power supply
board (7) terminals WL1-WL3 and WL5-
WL7. These terminals are directly over the
regulator board.
6.6
Replace the cover (1) using
procedure 2.
Note:
Refer to Figures 5 and 6 for the
following procedures.
7. Power or Sequence Switch Removal
7.1
Remove the cover (1) using
procedure 1.
7.2
Unsolder the three tabs that secure the
power switch board (9) to the switch.
7.3
Push the switch through the chassis (2)
front panel.
8. Power or Sequence Switch
Replacement
8.1
Push the switch into the chassis (2)
front panel.
8.2
Solder the power switch board (9) to
the switch terminals. For 100V and 120V
units, make sure the LED is lined up with
the panel hole labeled "Standby". For 240V
units, make sure the board's LED is aligned
underneath the "ON" position icon.
8.3
Replace the cover (1) using
procedure 2.
4.3
Connect the power supply cables back
to transformer (4) terminals 6-11.
4.4
Replace the cover (1) using
procedure 2.
Note:
Refer to Figures 3, 4 and 6 for the
following procedures.
5. Regulator Board Removal
Note:
The regulator board is not used in
the 1600
VI
amplifier.
5.1
Remove the cover (1) using
procedure 1.
5.2
Note the wiring configuration and
disconnect cables WL1-WL3 and WL5-WL7
from the power supply board (7) terminals.
This will allow easier access to the regula-
tor board (8). These terminals are located
directly over the regulator board in the
1800
VI
.
5.3
Disconnect the cables from the
terminals of the line filter (10) that are
next to the regulator board.
5.4
Remove the transformer (4) using
procedure 11. This will allow easier access
to the standoffs that secure the regulator to
the power supply board.
5.5
Unsnap the regulator board from the
nylon standoffs mounted on the power
supply board. This will also disengage the
regulator board from the power supply
J1 connector.
6. Regulator Board Replacement
6.1
Line up and insert the pins of the
regulator board (8) J1 connector (solder
side) into the power supply (7)
J1 connector.
