Old character into AC/DC? You might get stoned for that here (6)
I believe the answer is:
brunei
'you might get stoned for that here' is the definition.
The answer is a location as well as being a singular noun. This is suggested by the definition.
'old character into acdc?' is the wordplay.
'old character' becomes 'rune' (rune is a kind of character. I am not sure about the 'old' bit.**).
'into' indicates putting letters inside.
'acdc?' becomes 'bi' (I've seen this in other clues).
'rune' placed into 'bi' is 'BRUNEI'.
Can you help me to learn more?
(Other definitions for brunei that I've seen before include "major source of oil" , "Sultanate on the island of Borneo" , "Far Eastern sultanate" , "Muslim state" , "Its sultan is famously very wealthy" .)
