I'm repairing an A-1020 for someone, and now that I've got it working, I notice that it puts out some crazy heat. Particularly the 8 big grey resistors near the middle of the board... It's obvious that they are expected to get somewhat warm, as they are mounted well off the board and vent holes are found in the board underneath them.
But how hot is too hot? They got over 70 deg C... and that wasn't in Class A. Things really got warm in Class A - with the outputs and main heat-sink also rising over 70 deg C.
Should I be looking to find a way to reduce the temp of these resistors? Or perhaps put in parts that may dissipate the heat better without getting so hot?
