INSTALLATION
MOUNTING TRAY AND SHELF ASSEMBLY
Mounting holes have been spaced in the
shelf assembly to allow it to be completely
filled with trays of anyone type for the Gates
transistorized units. It is possible, where
maximum use of shelf space is not required,
to mix trays of different sizes. Thus a pro-
gram amplifier and preamplifier could be
placed at the left and a power supply at the
extreme right. Proceed as follows:
1 .
Locate the first tr ay at the extr erne left
or right of the shelf assembly, with the re-
ceptacle at the rear. The countersunk holes
ofthe tray w ill fit into the matching holes in
the shelf, when properly located. Leave a
1/16" space between trays.
2. Secure the tray to the shelf with the two
*4-40 x 1/4" flat head screws with the two
*6 internal'-external shakeproof washers un-
der two *4 hex nuts.

3. Determine whether or not the guide bar,
shown in Fig. 3, will be required. The pur-
pose of this bar is to prevent possible dam-
age to the mating connectors when upward
pressure is inadvertently applied to the am-
plifier during withdrawal.
The bar will be
required only where no other protecting ob-
struction is present in the rack, or where the
shelf is used at a location such as a work
bench.
It will not be required where another M6029
Shelf Assembly is mounted directly above,
or where overhead equipment interferes
Witt{~
mounting of the shelf due to the pr'esence'
of the bar. The mounting screws are locat-
ed so that they may be removed from within
the shelf.
4.
Mount the shelf in the rack using hard-
ware supplied with the rack. The two end
strips mount under the screw heads, and are
to be flush with the drop panel.
INPUT AND OUTPUT TRANSFORMERS
The input transformer is factory connected
for 150 ohms primary impedance, as shown
on the schematic diagram and on Fig. 4.
If
a terminated input is desired, a 150 ohm
resistor should be connected to terminals
9 and 10 on the amplifier mounting tray,
since the amplifier input is unterminated.

Fig. 4 - Input Transformer Connections
Refer
to
Fig. 4 for connection to 600 ohms
impedance.
If
a terminated input is requir-
ed, connect a 620 ohm resistor across term-
inals 9 and 10 on the amplifier mounting
tray.
If
6db more gain is deSired in some appli-
cations, the input terminating resistor may
be deleted.
In this case, however,
the
system component preceeding the amplifier
will not be properly terminated.
The output transformer is factory connected
