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.

Different amps, different temps! I am using 2 mcintosh 2205s and noticed one running hotter on one channel of heat sink then all of the others. After a thermogun and amp meter, I reset the bias and found a dirty connection. Read true maintenance manual from manufacturers to get specs. If you are technically apt, do it yourself! If not, find reputable repair or service.
