[Kenwood] ts940s - PCB burning

That is the way they run, very hot. Reflow the solder on them with good
solder and don't worry about it.

Hi Gang:
I need a help
A TS940S is with a part from the printed plate of circuit - RF unit -
blackened, but barely in the region of the transistors Q6, Q7 and Q8
(armored rectangular area).  Already verify everybody the tensions and RF
levels and is everything OK, but the transistors are heating more than the
normal one, causing problems in the solder. Soon after it link the radio the
transistors (and all the region in return) already are with temperature
above of the normal one Someone has some idea?
