2465 INOPERATIVE SWEEP
On the 2465 only, if you have an
inoperative sweep after going through
the power-up routine here is a
possible solution to the problem:
Unsoldered AlR752 from the board and
clip both leads to a length just long
enough to go through the board.
Re-solder the resistor back into the
board. Now, check to see if you have
a proper sweep.
If the leads of the resistor are too
long, there is a strong possibility
that one of the leads will short out
to the delay line shield on the
backside of the board.

A modification has been approved to
improve the terminals ability to make
good hard copies. This will also
reduce the time required to adjust for
a good hard copy.
The modification consists of replacing
the 4010-1 Hard Copy Tarsig Amplifier
card (p.n. 670-1744-XX) with the 4012
Hard Copy Tarsig Amplifier card (p.n.
670-2570-02), replacing the PlOO five
hole harmonica cover (p.n. 352-0201-00)
·with a seven hole harmonica cover (p.n.
352-0203-00) and setting up a new main
cable assembly {p.n. 179-1757-07), with
the seven ho 1 e harmonica cover, as a
field replaceable part. PlOO is part
of the 4010-1 main cable assembly. To
match the J number of the 670-2570-02
H.C.A. card, this will change to Pl59.
Wires in the new Pl59 harmonica
connector should be as follows:

An 050 kit, part number 050-1774-00,
has been set up to implement this
change in the field. The kit consists
of only H.C.A. card, the seven hole
harmonica cover and installation
instructions. This kit is available at
this time, but should only be installed
on an as needed basis.
