[QUOTE="John Roberts, post: 83427, member: 126"] Re: Behringer iNUKE NU6000 amplifier This falls under the category of "stuff happens".. I recall one issue with a new power amp roll-out, where a temperature sensing diode on the heat-sink was flaky. The difficult thing was that the part was a not a new part in the system, but had been used for years with zero problems. Coincidentally the vendor had recently transferred their manufacturing of the component to China. Purchasing and engineering had tested and approved a sample quantity of the new build parts, but full production revealed that they were problematic. I have seen similar such component failures from a number of big name vendors, some that the readers here will recognize by name, but I see no point in embarrassing them years after the fact. It is the nature of manufacturing that the product using these faulty parts will get the bad reputation for the failures, even though the engineering of these components is typically beyond the purview of the manufacturing company that uses the parts. I have had some good (lucky?) experiences with catching potential component problems by having quality assurance personnel perform random inspection of incoming raw components. Using statistical methods it doesn't take a very large test sample to identify a bad lot of parts (of course the vendor should be doing this too). With a little good fortune we discovered a problem from a major capacitor company, with all kinds of quality plaques on their wall.

Some of these simple components like a connector can be maddening to get to work flawlessly with the universe of slightly different mating parts. FWIW quality conscious component vendors will generally bend over backwards to correct such problems, when discovered. While the remedies available are limited. Be thankful that the problem is in a light weight amplifier. The old school heavy iron power amps cost a lot more to ship back and forth to rework. JR [/QUOTE]
