Kenwood 9103d current drain while "off".

I picked up a Kenwood 9103d mono amp with a problem. The amp works fine but the problem is when it is "off" it still draws current. The fan and blue light remain on as long as power is connected, regardless of voltage at P Cont. I thought it was just the fan drawing the current but I disconnected it and the amp still draws so it's not the fan circuit. I can hear something shorting inside the amp when power is connected. I'm going to try to see if I can find the culprit next time I have the amp open but was curious if anyone could point me in the right direction so I can know where to look . Thanks in advance.
