[QUOTE="dB-r, post: 5023037, member: 574699"] The only failures I have seen in Memphis 4K's are from vibration breaking the legs off the parts. In order to repair this, the right way, we have to do a full rebuild on it. It runs as follows: Rebuild Power supply alone and upgrade all soldering on all mosfets(outputs are good and not broken Rebuilt Output and upgrade all soldering on all mosfets Full Rebuild (replace all mosfets with new matched OEM parts and upgrade all soldering) $450 Yes, we are high priced repairing these but we do it right and that's the only way we do it, do not call or email or PM us bargaining, you either pay the price or send it elsewhere and we wish you luck. Yes we have rebuilt a few of these for competitors with no issues. Another likely scenario that you may have going on is a broken leg on one of the large rectifier or damper diodes, or a bad solder connection somewhere or could be some arcing from the bottom of the PCB to the top of the case/heatsink at high volume. Which you wouldn't need any parts for the repair so you would only be charged labor, which is $200. No free estimates on these amps, this is your estimate. No matter what it's gonna be at least $200, but it could be as high as $450. Don't send it in unless you are prepared to pay, we don't want your junk, we have enough used, non-Sundown Audio amps that we can't seem to get rid of. This amp is the same design, same exact parts and everything, just a different board, as the Soundstream XXX-6500D. [/QUOTE]
