Opti-Source Option Card
Test Setup Notes:
1. This unit is to be tested as installed in an
AmPlus™ 100 Amplifier.
2. The input levels are to be the actual
input level as measured at the connector,
and not the setting on the signal generator.
3. Set up the AmPlus 100 Amplifier as listed
in Table 1.
4. Set up the Opti-Source Option Card as
listed in Table 4.
5. On the AmPlus Amplifier, connect a
100 Ω, 100 Watt load onto the 70/100 V
output at J6. Place the Amp Mode Switch
S6 to the 70/100 V position.

6. In order to test the Opti-Source Option
Card using the AmPlus 100 Amplifier,
you will need the connector kits for both
products. The part number for the AmPlus
100 Amplifier connector kit that includes
J1, J4, and J5 is 188620-001. The part
number for the J6 connector is 190694-
008. The connector kit part number for
the Opti-Source Option Card is 187511.
7. If you must troubleshoot the Opti-Source
Option Card out of the AmPlus 100 Ampli-
fier Option Card Slot, you will need to order
the harness assembly used to connect the
main PCB of the AmPlus 100 Amplifier to
the Option Card slot. The part number is
188571-001. Be sure to run a ground wire
from the faceplate of the Option Card to the
AmPlus 100 Amplifier chassis.
