Re: Onkyo TX-NR609 New DSP chip fitted
It depends on the design engineer. I have seen logic chips designed by a EE engineer, who was a Professor, run on two volts and they supplied 5 volts to these chips. The thinking is the rest of the energy would give off as heat. The problem was found that the fuse keep blowing. My manager got rid of the fuse and replaced it will a paper clip. After running it for 24 hours it started on fire. The answer was to put a fan on top of the boards to blow air through them. This took care of the heat and if the fan did not run the unit did not turn on or run.
