Hello, is it normal for Beomaster 300o-2 Right side output transistors to get hot while idle. Heatsink gets hot to the point that i’m not even able to touch it. Thanks!

Hi,

No that is not normal. In most cases it is the idle trimmer in the output stage being defect. Try to replace it and trim it in according to the service manual.
