Parts List Amendments
At the front of the parts list is the Parts List Amendments box (an example of which is shown
below). This box contains a list of component changes which took place after the parts list and dia-
grams in this section were compiled. These changes (e.g. value changes, added/deleted compo-
nents, etc.) are listed by circuit reference in alphanumeric order and supersede the information
given in the parts list or diagrams. Components without circuit references are listed in IPN order.
The number in brackets at the end of each entry refers to the Tait internal Change Order document.
Variant Components
A variant component is one that has the same circuit reference but different value or specification in
different product types. Variant components have a character prefix, such as “&”, “=” or “#”, before
the circuit reference (e.g. &R100).
