I have noticed that people (IE Brian and Peter) have tended toward component diodes in power supply kits for "gainclone" amps and was wondering what the benefit (if one exists) of these over pre-packaged bridge rectifiers was.
Most of the electronics stuff I do is for instrumentation, so I am still quite new to understanding the sonic implications of different electronic components in amplifiers.
Thanks for helping out the new guy!

Thanks for the response, Tweeker!
Taking this one step further, in a non-regulated power supply, I was under the impression that most of the power draw would be from the capacitors, and that the diodes would be effectively masked-especially in the case of the snubberized unit where the caps are so large. I guess I am not seeing the benefit of soft recovery diodes when the output of these will be fed into caps where the recovery will be "buffered" (not sure if this is the right description) anyway.
As for using Schottky diodes, I am plain lost on that one. I would think the voltages we are using would be sufficiently high to nullify any benefit of Shottkys.
Knowing how many revisions that the chipamps have been through, I am sure there is a justification for the diodes, but I just don't get it quite yet.
Thanks again!

PS I could, of course, just use the diodes and be done with it (it's not like they cost that much) I just have a nagging feeling anytime I do something without understanding why!
