Use only
*l%
deposited carbon film resistors for R24,
R25, R27, and R28 a s previously described for R26.
Again common type composition resistors can be
used for series pads provided they do not exceed 10%
of the total resistance value.
On the "X10OV' range only, a fixed High-Q ceramic o r
silver mica capacitor connected in parallel with
R28 will compress the high frequency end of the
band. The maximum value f o r this capacitor is
300 ppf and any value l e s s than this may be used.
This capacitor is not required in a l l instruments
and is not shown on the schematic diagram.
10) Replace the cabinet o r the top and bottom cover.

POTENTIOMETER
Replacement of the frequency control potentiometer
involves two basic operations:
1) The mechanical procedure for replacing a de-
fective potentiometer with a new one.
2) The necessary electrical adjustments described
in paragraph 4-13.
All necessary specialized instructions a r e included
with the replacement potentiometer.
