Using discrete diodes instead of rectifying bridges.

[mrfeedback]

Peter, there was discussion here of 'snubber' networks across diodes a while back - worth rereading.

Re: 43CTQ100

Can it be used with rails +/- 45V DC?

Should be no problem, but u may not be comfortable with the margin (I'll be using the 43CTQ100 for the Aleph 5 PSU). It's better than ultafast soft recovery diodes as it has no reverse recovery.

43CTQ100

I have never got Schottky diodes to sound as good as soft recovery types. I also don't think 100 volts is sufficient margin.
