Hi.
I think the answer may be
idiot box (ie a television) although the exact wordplay escapes me or the clue seems incomplete ... (it's most probably me) ...
I wonder what the answer to either clue 1a or 1a is?
'box'= 'strike' ... after 'I'/one + first letters of 'often' & 'to' ?? But then the first 2 letters of the word 'idiot' are still unaccounted for...
