Need Help! My Class A Amp Is Running Very Hot

Hi, currently I own a Luxman 590 Class A 30watts Integrated. After the unit running for more than half an hour if I put my hands on the top of the cabinet over or around the vents  it is burning hot , I even feel the heat on the sides of the cabinet, other than that the amp sounds good. Can anyone tell me if that’s normal or I should get it check out?
Thank you  in advance for your advice.

This is a funny amp, @pbnaudio


Look at the power rating, and look at the idle/max wattage.
Tell me what they say to you. :)

I've had Class A amps for years so to me what you're describing sounds normal. Looking at a picture of the inside of the 590, each of those massive heat sinks is for only four power transistors. That tells me the designers expected all that heat.

@khmyjy- Luxman has it covered. Just relax and enjoy your music.

I'd still be interested in having you take a few temperature readings at various locations using an infrared thermometer.

My WA33 woo runs extremely hot to ... to the point where if I put my hand on the chassis it will burn my hand ...literally...  I bought a fan to cool it off so it runs warm all the time now....
