Like a radio, it's worth having (5)
I believe the answer is:
asset
'worth having' is the definition.
I can't judge whether this definition defines the answer.
'like a radio' is the wordplay.
'like' becomes 'as'.
'a radio' becomes 'set' (I've seen this in other clues).
'as'+'set'='ASSET'
'it's' is the link.
Can you help me to learn more?
(Other definitions for asset that I've seen before include "Something valuable to have" , "Anything considered valuable" , "valuable sort" , "Boon" , "Valuable person" .)
