Regulated Power supplies

[ALW]

Perhaps

Perhaps the phenomena in question has something to do with the relationship of the inductance of the secondary - the resistance from the secondary to the capacitors - the capacitance - and the waveform ??

You could just be right...

Found it

After listening a couple of days and re-connect one 15,000uf to each supply rail. The result is much better now, everything is balance;

3 X 15000uf per rail; sound strangled, max out bass
2 X 15000uf per rail; balanced sound
1 X 15000uf per rail; excelent dynamic, but thin sounding

All above bias Iq at 4A for Class A mono blocks

regulators and transient response....

I was going to use a regulator on my project, but my teacher talked me out of it. He said that it results in poorer transient response. Is this true?

 

[jackinnj]

a regulator has to sense

the error voltage and then respond to it -- this takes time and compensation.

This is turning into a perfect thread (order of replies):

1. Technical issues
2. Economic issues
3. Personal issues/interpretations

If all DIYaudio threads were like this, it would be awesome!
