For instance, radios and televisions can be valuable items (6)
I believe the answer is:
assets
'be valuable items' is the definition.
(an asset is something valuable)
'for instance radios' is the wordplay.
'for instance' becomes 'as'.
'radios' becomes 'sets' (I've seen this in another clue).
'as'+'sets'='ASSETS'
'and televisions can' is the link.
I am not very happy about this link. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for assets that I've seen before include "(Person's) property" , "Personal wealth" , "Useful skills" , "Resources or holdings ( 6)" , "Useful or valuable possessions or qualities" .)
