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.

Contact the dealer or manufacturer directly and explain the situation.

This is not normal.  Don't take any chances.

Doesn't matter what the problem is, and there is a problem.  If you aren't prepared to fix it your self, then an authorized service center or the manufacturer is the way to go.

It appears to me that the bias is way off. However, a simple solution (not the best) is to adjust the bias back to where it should be.  However, what caused the bias to float way off in the first place.  This is not normal.
