The one that went up in smoke yesterday in my brother-in-laws was a WX make
and has the same numbers on it like the picture in msg#43297. Mine is also a
WX make, has the same numbers, but has not given me a problem as yet, and
runs cool. I put the 4 ohm resistor in the speaker line and also put a 12V
regulator on the red receiver power wire. No problems with mine yet.
