CRITICAL LEAD DRESS
1. Do not
permit any
strains
to
be
placed on the leads of R126, R157,
R158, R164, R165,
R173, R188
and
R191.
Do not
permit
these re-
sistors
to
be exposed to
the
heat
of a
soldering iron
any
more
than is absolutely
necessary.
2. Dress
the
temperature compen-
sating
resistor R191
approxi-
mately
one-quarter
inch
from
the
power
transformer and
the
chassis.
3. Dress
all video
coupling capaci-
tors and
peaking
coils up
and
aivay
from the
chassis.
4.
Contact
between
the r-f
oscilla-
tor
frequency
adjustment
screws
and
the
oscillator
coils or
chan-
nel
switch
eyelets
must
be
avoided.
