Same sad converts got together (7)
I believe the answer is:
amassed
'got together' is the definition.
(got a mass of something together)
'same sad converts' is the wordplay.
'converts' is an anagram indicator.
'same'+'sad'='samesad'
'samesad' anagrammed gives 'AMASSED'.
(Other definitions for amassed that I've seen before include "Mad seas (anag.)" , "Gathered together" , "Heaped up, accumulated" , "Got up" , "Gathered in great quantity" .)
