Hello fellows, greetings from crumbling germany, I just bought a SBC. A few remarks:
First, the SBC power supply generates a voltage of 15,xx versus ground. I grounded it on recommendation of the Hifi dealer, because the amplifier itself by intended design wasn't grounded on connectors. So far, by doing so I got rid of the significant hum the SBC created before. Second, people here are discussing power supplys. Why not trying the best supply first? That is, four (four, not more. And no non-rechargable batteries please...) NIMHs. This provides 5,6 Volts unconnected, and ~5,0 Volts connected - Voltage sinking slowly. I tried that, and for now, the SBC didn't explode. The SBC starts at 5,10 and stops working at 4,30-4,20 Volts here. It sucks up 700 up to 900 milliamps (0,7 to 0,9 Amps), depending on display brightness. The current varies slightly all time. So if you try NIMHs first, you can easily test wether this or that superior power supply will make a difference. If you got some spare time, you may play around with an adittional fast fuse (probably 1,x to 2,0 amps), and some condensers.for even smoother current, if possible at all. I doubt there is any considerable noise in NIMH voltage. Dont forget: The plug must be + inside, and - outside. -- NaimSqueezer ------------------------------------------------------------------------ NaimSqueezer's Profile: http://forums.slimdevices.com/member.php?userid=25953 View this thread: http://forums.slimdevices.com/showthread.php?t=59264 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/audiophiles
