Levinson 331 leaking black tarry material

My trusty old levinson 331 has been collecting dust x 2 years. It was left unplugged in upright position. Last week when cleaning around it, i noticed thick black tarry liquid was spewing out of the power cord socket. I removed bottom panel and found more of it on the inside of the rear panel where the connectiins for power, rca, communications link. I was guessing electrolytic fluid from one of the caps but i doubt it. Gravity shoyld have pulled the liquid down onto the bottom panel right??? Not a drop there. I remived the top panel also but that did not reveal anything. No rubber or plastic melted from top panel. Or gaskets. Is there an easier way to post pictures? Not sure i still have photobucket.
