CHAPTER 1
INSTALLATION
1.1 INTRODUCTION: When setting up
the station, provide adequate ventilation for
the amplifier. Also, select a location that
allows comfortable access to the front
controls and adequate clearance for rear
panel connections.
1.2 ELECTRICAL CONNECTIONS:
The TITAN III amplifier draws up to 20
amps at 240 VAC. Care should be taken not
to overload house wiring circuits usually
fused or circuit breakered at 15 to 20 amps.
A straight run circuit with # 10 / 2 wire with
ground and breaker or fuses at 20 amps is
strongly advised. Do not connect the TITAN
III to AC voltage until installation of HV
power transformer is completed.
1.3 HIGH VOLTAGE TRANSFORMER
INSTALLATION: DO NOT CONNECT
THE AC LINE CORD TO 240 VAC WALL
OUTLET BEFORE INSTALLATION OF
THE HV POWER TRANSFORMER.
Check to make sure the amplifier is
unplugged from the wall. Remove the top
cover of the amplifier. Note only 8 screws
were initially installed at the factory. This
was done to simplify your task. Four of the
screws are in the underside bottom edges
(two long and two short). Temporarily
remove the left side chassis rail (four short
screws). There are four 10 x 32 nuts (TEN-
TEC part #54005) in the packing kit. You
must use these to mount the transformer and
not the nuts in the transformer shipping
carton. Identify the large open area in the
chassis where the transformer mounts.
Note the location of the four threaded studs
in the chassis. Start two nuts only on the
two studs closest to the center of the
amplifier chassis. Just “start” the two nuts,
engaging only a few threads. Orient the
transformer with the two wire HV lead side
of the transformer coil toward the center
chassis shield. Being careful not to disturb
the printed circuit board behind the meters,
align the slots in the transformer bottom
mounting bracket under the two nuts that
you just installed. Slide the transformer
toward the shield until the studs are seated in
the transformer mounting slots about
midway. Align the slots in the other bottom
mounting bracket with the two remaining
studs in the floor of the chassis near the
outside of the amp. Install the two
remaining nuts on the open studs. Using a
long nut driver or socket, tighten all four
nuts. Connect the two wire HV cable to the
socket on the HV rectifier board A2 (81944)
mounted on the center shield. Note the plug
will seat properly in the socket in one
direction only. Visually inspect the
connection for proper seating. Connect the
four wire primary cable to the four wire
cable extending from the rear chassis area
near the smaller low voltage transformer.
Again this plug will only seat properly in
one direction. Care should be taken when
re-installing the side rail and top cover not to
pinch this cable. Excess cable length may
be looped and tucked between the side rail
and fan housing scroll. Remember to install
all 34 screws in the top cover when re-
assembling. The extras you need are in the
packing kit. To access the five screws along
each bottom edge, carefully tilt the amplifier
on it’s side or slide it to the edge of the table
and work from below. Note that the front
two screws in each bottom edge are longer
than the rest (4 long screws total).
Never ship or transport the amplifier with
the transformer installed !!! Serious
damage to the chassis may result.
