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.

Did you ever call Luxman or your dealer? What did they have to say?

just want to be sure it’s ok since it is a preowned unit
Obviously, most amps will survive life with higher input voltages but it's not necessarily good for them, best to ask the manufacturer run at 122 Volt continuously for the L590AII is OK!

I'm reading this because I have a class A tube amp, and had been on for several hours. It started to overheat, by not letting controls work. It's fine now, but I'm buying a clamp fan to help ventilate.
