Oracle: Find control characters except line feed

I'm trying to all rows where a column contains any control charters with the exception of the line feed character (hex value of A). I've tried the following, but this only returns results that have a control character and don't have a line feed. I really want the set of characters that are control characters, LESS the line feed character. Is there a 'minus' operation for character sets, where you can exclude particular ones from it?

SELECT *FROM MyTableWHERE REGEXP_LIKE(MyColumn, '[:cntrl: &&[^' || UTL_RAW.CAST_TO_VARCHAR2(HEXTORAW('A')) || ']]{1,}');

Any thoughts?Thanks!
