Hi Drow,

Thats a serious power supply. Tell me a little more about the resistors in series with the rectifier diodes.

According to chip manufacturer due to the large cap at the output you may need a reverse biased diode connecting input to output to safeguard against input short.

Nice job

Default more curves

Are these the ultimate curves for home audio reproduction ? Without the need to butcher the sound again in the home. Or does every home have its own rules ?

Natural environments are treated for sound reproduction, by the trees and the grass.

[The need for crossovers to separate the high from the low is necessary because our ears know that the full audio spectrum cannot emanate from the same membrane at the same time, it is totally unnatural.] TRUE or FALSE

Watch this space as Drow hits the home stretch and brings in the verdict

Contribute to the state of the art by bringing in your verdict also , all ears accepted.

All the best

Hi Joel,

You may not need the protection diode since you have a discharge resistor at the output and the input isn't shared with others.

kind regards,

Harrison.
