Hello ck
thanks a lot for your reply. In my innocence it never occured that the new component could be faulty. I've got an old Megga tester which ought to do the trick for insulation test. After that small blow torch should 'cook' the new element if necessary. I'll let you know how I get on although it might not be for a few days.
Can't wait to get back to cheese on toast.
Regards
Tony Shaw
