How hot?If you can touch the heat sink for a while means it is OK.
You can check the voltage on one of the 0.22ohm. If meter read
about 10mv to 14mv, I asscume average 13mv means total 350
to 360ma idle current.If the voltage too high you can adjust the
pot locate at middle the power pcb.Make sure you turn a little bit,
then check the voltage.The idle current decide the output watt
in class A mode.You do not want to set it too low.
