talkback is usually from positive of external speaker to positive of pa, or ext. spkr to chassis ground...negative of spkr or pa shouldn't do anything...make sure there are no solder points still touching where they shouldn't be Sean CEF867 CVC81 "Keep smiling, it makes people wonder what you're up to!!"
