Rectifying bridge.

Sean, sounds like a digital RF amp ur talking about...maybe even a class E? Stil hard to see how 1% suply voltage change alters the output 18%... sounds like these are switching diodes, not rectifying power diodes.

Anyhow you want soft recovery diodes, like HexFreds, fast recovery and turn on will usually add to the noise...

sometimes changing the diodes will really help, sometimes not. Try it.

The diode bridge converts the AC voltage out of the transformer (after being converted to a lower voltage). The only ways it can offer improvement are:
1) little more reliable
2) Because it is operating at a lower percentage of its rated voltage, it may have lower reverse voltage leakage currents that may somehow improve the sound.
3) Being higher voltage may mean that it has less capacitance input to output which would help keep noise from passing thru.
That all I've got.

Bear, Thanks for the info about the fast recovery type adding noise. What about Hexfred's vs Schottky's for an SS preamp or power amp ? Sean
