There is a lot more to the 0V line than just current handling capacity. |

For example the circuit I posted in another thread. |

Besides which, are you really suggesting that you dedicate a whole discrete audio amplifier to generating a 0V rail- surely not. |

--- Quote from: Audioguru on January 09, 2019, 09:49:22 pm ---Usually the (+) input of an opamp or power amplifier is at 0VDC and draws VERY low current. Then the rail splitter does not need high power ICs, instead the rail splitter is two medium value series resistors across the supply and their junction is 0V. --- End quote --- This is one of your famous sweeping statements AG. :) |
