Denon Receiver, faint dirty/burning smell ?

I open a little window so a little bit of cold air breeze goes through appartment it helps a little bit... but it also gets kinda cold... and still stinky nasty smelly is there now and then so not cool.

Bye, Skybuck.

Once it gets to the stinking stage, finding the hot part should be easy. The circuit board should be brown around it.

There are two types of components that I've seen get stinky in an amp.

First is the output resistors when component failure has caused incorrect bias or oscillation. These come in pairs and you'll need a tech to fix this unless you know audio circuits.

Second is an aging/undersized resistor driving the low voltage circuits from the high voltage lines. This would be a single hot resistor next to a three pin semiconductor that is also hot. Just solder in a replacement with the same resistance (from the label, not measured) but a higher wattage.
