Tables Joined On Multiple Columns, Exclude Records Found In Table A

I'm using SQL server 200

Table A has columns CompressedProduct, Tool, Operation

Table B in a differnt database has columns ID, Product, Tool Operation

I cannot edit table A. I can select records from A and insert into B. And I can select only the records that are in both tables.

But I want to be able to select any records that are in table A but not in Table B.

ie. I want to select records from A where the combination of Product, Tool and Operaton does not appear in Table B, even if all 3 on their own do appear.

This code return all the records from A. I need to filter out the records found in Table B.

SELECT ID, CompressedProduct, oq.Tool, oq.Operation FROM OPENQUERY (Lisa_Link,
'SELECT DISTINCT CompressedProduct, Tool, Operation FROM tblToolStatus ts
JOIN tblProduct p ON ts.ProductID = p.ProductID
JOIN tblTool t ON ts.ToolID = t.ToolID
JOIN tblOperation o ON ts.OperationID = o.OperationID
WHERE ts.ToolID=66
') oq
LEFT JOIN Family f on oq.CompressedProduct = f.Product and oq.Tool = f.Tool and oq.Operation = f.Operation
