WCT3 PARTS LIST
Each type and value of a surface mount component, (indicated by
"[smt]"), is placed in its own labeled baggie. Be aware not all [smt] com-
ponents have value markings so be careful not to mix them up. In the
parts list an "X" in the reference designation indicates that an extra com-
ponent or two is provided because they like to "fly away" due to the
small size.
