Everyone kept telling me not...Strange experienced.. Everyone kept telling me not to go over 84 volt or else the chip would die. I have many of these little LM3886T, so I took the risk in testing one of them. I have a power supply that can produce +-36ct or +-48ct at 4amp. I am using the same size heatsink as in the picture without the fan. I first tested with +-36 parallel of 6 speakers, probably some loss through the wires but this brought it down to 2ohm. It sounds great playing "AC/DC Who made Who". Pretty loud with lots of punch. The heatsink was warm but nothing hot. I then switched it to the +-48, this is 96v total exceeded 12v, thinking it will die or not produce any sound because of the SPIKE. Well, it played the same "Who made Who" louder with stronger punches. I left it playing for days, thinking it could only max out for a short amount of time. It didn't give up. The heatsink was hot, but wasn't melting crayon hot. I measured the voltage at the chip's pins, taking in 96volt. when I turned it up full power, the voltage dropped a bit, but it was still 94volt. Has anyone tried higher volts?Anonymoushttps://www.blogger.com/profile/10022067625746301094noreply@blogger.comtag:blogger.com,1999:blog-4191887753331304313.post-12684849765877346332016-05-23T09:32:00.826+03:002016-05-23T09:32:00.826+03:00Thank you very much for your guideThank you very much for your guidetozeyanahttps://www.blogger.com/profile/08116968500023474225noreply@blogger.comtag:blogger.com,1999:blog-4191887753331304313.post-13017042878590052412016-05-23T03:48:10.349+03:002016-05-23T03:48:10.349+03:00It will work with 4700uf, but you will get strong ...It will work with 4700uf, but you will get strong ripples when you draw higher current.Христоhttps://www.blogger.com/profile/14002909704834630953noreply@blogger.comtag:blogger.com,1999:blog-4191887753331304313.post-7580030616124447672016-05-22T21:20:49.523+03:002016-05-22T21:20:49.523+03:00Thank you very much.
