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.

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.

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....

I have a 100 watt per channel pure class A Threshold SA/4e. There are large heatsinks along both isides of the amplifier. The heavy front face of the amp, and the large rack handles, are also part of the heat sink system. After it's been working for a half hour or so, the heat sinks get up to about 114 degrees F.
