How hot is too hot?

When i leave my Parasound Hint 6 on overnight, it is hot to the touch (top grill), not warm, in the morning. There is nothing on the sides and 6 inch clearance on the top.I even tried switching the input to something nothing is connected to - like AUX or PHONO. Doesn't help. I have to turn it off now when i don't use it. No big deal, but it seems like something must be wrong to produce that much heat when not in use.

Is this normal? What part of the unit produces that much heat? What can i do?

I would have to say there's something wrong. I have a Hint 6 and it stays on 24/7 and I wouldn't say it's anything more than warm.

The Halo 6 has the main power switch on the rear panel, so the switch on the front panel is a standby. Do you turn the volume all the way down to zero after listening? If you don't, try that. If you do, turn the front panel switch off after listening and back on 1/2 hour before listening. Always leave the rear panel power switch on.

Obviously turn it off overnught if not playing..
Class A runs hotter on idle. Just warm it up BEFORE play, off after. 
Prepare to pay the power company.

You have to measure the temp of both heat sinks under the hood with an infrared thermometer. If one is much hotter than the other, then it's a problem. Heat sinks shouldn't vary by more than 5 to 10 Celsius. If both sinks are the same temperature and the amp isn't tripping off on thermal overload protection, then it's okay. Unless you fiddled with the bias adjustment pot, which I assume you didn't.

Turn the dang thing off. On, wait 20 minutes, play!
