TDT50 & TDT150 INSTALLATION INSTRUCTIONS

1. Disconnect AC power from the amplier.

2. Remove the amplier top panel by removing 17 screws
(6 on each side, 3 on back and 2 on front).
Please note that front screws are longer.

3. If the mounting bolts have two nuts, remove one and
save. These nuts will be used to hold the transformers
in place. If the mounting bolts have only one nut, do
not remove. Transformer will be held in place with
supplied nut.

4. Install transformers as shown in gure 1.

5. Locate the amplier circuit boards and jumpers.
Each amplier card represents two individual output

channels; one odd and one even (refer to gure 2 for
reference).

6. Using a pair of pliers, remove the black and red jumper

from the associated amplier channel.

7. Following the diagram below (gure 3), connect the

wires as indicated.

Please note that wires on odd channel are

mirrored from wires on even channel.

Brown wire = 25V
Orange wire = 70V
Yellow wire = 100V
