Put out note, second-hand (6)
I believe the answer is:
doused
'put out' is the definition.
(I've seen this before)
'note second-hand' is the wordplay.
'note' becomes 'do' (musical note, as in do-re-mi).
'second hand' becomes 'used' (I've seen this before).
'do'+'used'='DOUSED'
(Other definitions for doused that I've seen before include "Extinguished, threw water over" , "Extinguished or soaked" , "Plunged something into water or extinguished a fire" , "put out" , "Drenched with liquid" .)
