Hi Jeff
Yes, the location number for HOT is Q402, not Q804 as in the repair tip. I
have my eyes on it as we speak. HOT is definitely Q402 and crosses to an
NTE 2353, while Q804 I think crosses to an NTE 379 - major difference. I
don't yet have my parts to complete this repair but I will keep you updated.
The service bulletin said, "For thermal runaway of Q402, add a 33 ohm 1/4w
resistor to Q402, Base to Emitter." There are four bulletins on this that I
could find.
