7.3.1 Oscillator Module Removal/Replacement
If a fault is found that requires the replacement of the Oscillator Module (Assembly A1) follow the
following steps and refer to
Figure 7-1 for the module locations:
1. Turn off the front panel circuit breaker. Remove the input power from the rear panel
terminal block.
2. Remove the top cover.
3. Remove the front panel knobs.
4. Remove 5 screws that hold the oscillator assembly to the front panel. The oscillator
assembly can now be removed.
7.3.2 Amplifier Removal/Replacement
If a fault has been found that indicates the failure of the amplifier module (Assembly A7), check
the condition of the +300 VDC fuse (F2) before replacing the amplifier. Refer to
Figure 7-1 for the location of the fuse.
If it is determined that the amplifier module must be replaced, perform the following procedure:
1.
Turn off the input circuit breaker.
2. Disconnect AC input power at the rear panel.
Remove the AC Power Source top cover by removing (13) #6-32 x 5/16” FLH
screws.
Remove the (2) #6-32 x 1” screws and lock washers that hold the amplifier module
along the left chassis side panel.
Remove (2) #6-32 x 3/8” screws and lock washers located near the connector,
attaching the red insulator to the center bracket.
6. Remove the amplifier by pulling it away from the connectors and lifting it up and out of
the amplifier cage.
7. The amplifier may be replaced by following this procedure in reverse order.
8. Check the amplifier 20 A fuse (F2) located on the DC Supply Board, A6, and
replace it if necessary.
9. After an amplifier has been replaced, readjust its gain.
