[QUOTE="dB-r, post: 6207087, member: 574699"] No they all sold out in like 4 hours at that price.... The problems vary greatly, too long to list here. No common problems among the amps, well actually the older SAZ models tend to break from vibration, but the newer ones do not, have not seen a single vibration failure in those. This is probably due to the nice feedback I give Jacob so he can tell the factory how he wants HIS amps built, regardless of what the factory says. Standoffs were added into the new heatsink SAZ models in the middle of the board to stop the board flex. It has been VERY effective at resolving the problem. Probably why we hardly see ANY SAZ-1500D's come back anymore at all. We used to get alot of them, and most of the were vibration damage, we hardly ever get one of the new ones. Saddens me really, because they were a great seller in refurbished. We do extra soldering on ALL of the refurb amps to help even further strengthen them against vibration damage, it helps the older model SAZ amps tremendously. I have only seen 1, that was over a year since we refurbed it that was broken. And it didn't break our soldering, it broke the legs right at the base of the part, which unless International Rectifier wants to spend millions to make stronger legs on those TO-220 mosfets, there is nothing we can do to prevent that. This does not occur in the newer SAZ amps that have the standoffs. Improving your product over time is important. Sundown does this. [/QUOTE]
