Well if u cant get us fixed for $50 then trade it. DB-R will charge u a good bit more then $50 I assure you. So non working amp for wrking amp sounds fair as long as the solid does the power u need.
Db-r will never get any of my amps after the way i was treated on the phone then he refused to even look at my amp another shop quoted me 300 timothy webb a user on here is the one who said he could could do it for around 50
