| My newly built power supply is blowing fuses. |

| coppercone2:
maybe the designer had something in mind but fucked up. the values used are indeed preposterous. If you guess at the inductance of the resistor being 25uH and the 100n cap and negate resistance its centered at 100KHz. |
| Hextejas:
It is not my design. I borrowed it from the DIYAudio site. |
| Hextejas:
If any of the critics would like to change it please do. I will go ahead and build it and see how it performs. It needs to support a left and right pair of either 4 ohms or 8 ohms. I would be curious to see if it makes a difference in the sound. |

All modifications I'd do is removing some unnecessary parts and not use audio grade capacitors (especially when using not in signal path) as they generally are just usual good quality caps sold for a lot of money. But as they are already mounted, there is no point of removing anything as it won't make any difference. |
| wraper:
Only things somewhat worth of removing are R1, R2 bleeding resistors. Amplifier will discharge capacitors by itself anyway and those resistors will cause some additional heating without adding any benefit. |
