This is a cosmetically beautiful Marantz 2150, but inside is a disaster. So far I’ve restored much of the power to the receiver, but there is a long way to go as the driver board was destroyed by another “shop”
Can you spot in the picture what they did incorrectly that would have melted down the entire driver board?

Looks as if the legs grounded to the heat sink? They did not pull the insulation tubing up through the holes it looks like.
