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.
