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.

IMO it probably is running as it is designed to run.  I have a Luxkit amp that runs hot, very hot to the touch so you wouldn't leave your hand on the unit and it has open vent slots but small heat sinks.  The kit has been around 30 years and works fine, sounds fantastic also.  One of the best sounding amps I have ever heard or built myself.  Oh course mine is slightly modified by me!

BTW the Luxman will wipe the floor with the First watt amp so I wouldn't even consider that move.

Happy Listening.
