METER CIRCUIT BOARD
PARTS LIST
Refer to the Pack Index Sheet and locate Pack #4.
Then remove the parts from this pack and check
each part against the following list. The key
numbers correspond to the numbers on the "Meter
Circuit Board Parts Pictorial." If a part is packed in
an individual envelope, with the part number on it,
identify the part; then return it to the envelope
until a step calls for it. Do not throw away any
packing material until you account for all of the
parts.
To order a replacement part, always include the
PART NUMBER. Use the Parts Order Form
furnished with this kit. If a Parts Order Form is not
available, refer to “Replacement Parts" inside the
rear cover of this Manual.
A replacement part may look slightly different than
the original part, or may have different printing on
it. In any case, the performance of the replacement
part will meet or exceed the requirements of the
original part. For example: A 15-volt capacitor (10
HF, 15 V) may be replaced with a 25-volt capacitor
(10 pF, 25V).
