AM/FM Stereo Tuner
Addendum
The
AM/FM Stereo Tuner User and Assembly Manual
is written with the assumption that the user
has purchased the product from WhitakerAudio as a ready-to-assemble package. For builders that
have acquired the components on their own and are using the manual as an assembly guide, it is
recommended that the parts be divided into the packaging referred to in the manual.
In the process of acquiring parts for this amplifier, a number of vendors will be used. As such,
parts will arrive lumped together and will also arrive at various points in time. The process used
by WhitakerAudio involves organizing the components into three major groups:
•
AM tuner printed wiring board (PWB) components
•
FM tuner PWB components
•
Chassis components
Parts are organized by component number and device type. For example, all 1 k
Ω
1/2-watt
resistors for the AM tuner PWB are packaged together. Each group of parts is placed in a
resealable (clasp-type) envelope with a self-adhesive label applied. Labels such as Avery #5260
are useful for this purpose. Recommended envelopes include the following:
•
2.25-inch by 3.5-inch envelope (Staples no. 1 coin envelope)
•
3-3/8-inch by 6-inch envelope (Staples no. 6 coin envelope)
•
6-inch by 9-inch clasp envelope (Staples)
While this sorting requires some up-front organizational time, it serves as a check that all parts
are accounted for and speeds assembly of the PWBs and chassis.
The following tables list the labels used for the three component groups.
