As always I am well behind everybody else and still need two answers before embarking on the endgame. 19A - Local chap with tips for ethnic translator (5). I think the answer is a piece of computer equipment. 30D - Occasionally, coach ends up in past form (4). I think the answer is an art form and that this will result in a clash. It is possible the unchecked letter in 19A is the same as the first letter in 30D. Time to take a break from this to refresh both mind and body.
