During discussion of the idle voltage and bias current on the 1010 in craxx6969 1010 recap thread http://www.audiokarma.org/forums/showthread.php?t=505747 it was brought up that the 1010 manual was wrong in the value for the bias @ 50mv between pins 14 & 16. Also this thread from last year seems to verify the error on the 1010 http://www.audiokarma.org/forums/showthread.php?t=460892 and the question was raised for the 939.
As the 939 is Similar (although both amps are on the same board instead of separate boards on the 1010), would the adjustment error apply to the 939 or is the setting of 50mv correct.
Neither of mine get hot, or what you would term very warm. More lukewarm in that @ idle I can comfortably put my hand directly on the heatsink and hold it there for at least 15 seconds. When run hard the 939 heats up some in that it starts to get uncomfortable after 15 seconds. I know this is subjective but it is longer than the generally accepted 10 seconds.
