UNPACKING YOUR KIT
To ascertain if you have received all of the parts required to build this kit, you may check the
parts against the PARTS LIST.
When unpacking each kit, handle all the parts carefully so that you will not damage any delicate
DO
components .
NOT throw any packing material away until you have completely checked all the
components . In some cases, there may be a loose component contained within the packing. In any
case, whether you check the components against the parts list or not, it is advisable that you keep
the container and the packing material stored some place until you have fully completed the kit.
ME THOD OF PART IDENTIFICATION
To enable rapid identification of electronic parts , each part has been assigned one or two letters
of the alphabet called a "reference designation". These "reference designations" are nothing more
than an initial letter or two representing the name of the part. For example, a tube socket has been
assigned the "reference designation" letters "XV" and a resistor the letter "R".
ten sockets and 20 resistors in your kit, these parts would be identified by the designations XVl
through XVlO and Rl through R20, respectively.
JACKS
The reference designation assigned to receptacles (often referred to as jacks or binding posts)
is the letter J. The different types of jacks used in this kit are so lettered and illustrated here as
well as in the construction steps. In some cases, more than one jack is mounted on one bakelite
strip and it is so noted.

SWITCHES
The reference designation assigned to switches may take several forms such as : switches that
may be mounted on potentiometers and rotary switche s .
O n ROTARY SWITCHES , the front of the wafer is assigned one letter o f the alphabet and the
rear a second letter. Thus the front of the first wafer on S 3 has been assigned letter
the rear has been assigned letter "B".
