Pound Robin II

Each down clue, except the first, has a misprint in the definition; the discarded letters must be used to replace letters in the completed grid. Each across clue, except the first, has an extra letter in the wordplay which must be removed before solving; these letters in clue order hint at how to produce the final grid. All entries in the final grid are real words. Chambers Dictionary (2016) is the primary reference.
