HarryH, why 9610s' ? Voltage rating of the 9510's should suffice. I think they would have lower capacitence.

I pretty much agree with all your mods except this one .... the best diodes in a power supply to minimize garbage are probably ultra soft recovery diodes... many of these are also fast switching but if you used fast recovery diodes you may actually find more noise on the supply rails.

Default Diode diatribes

I agree that soft recovery is one of the most important criteria in
diodes in this application. The IXYS diodes are excellent in this parameter. I have listen to high speed soft recovery diodes
from GI, Motorola, Harris, IR and really like the IXYS parts. They are getting the reputation as one of the best sounding diodes for
audio supplies. Do some research. Talk to some tweaks. I think at least a couple of high end part sellers are carrying them. I bought mine at Digi-Key. Go to the IXYS website and check out the datasheets and app notes. I also think that synchronous rectification using Power Mosfet has some promise as it is being the de facto approach for switching power supplies for maximum efficiency.

yawn............ next?

well then, i think it's probably money well spent .... just wasnt sure that these diodes were soft recovery as you did not state that in the original post and i was too lazy to go find out for myself it's also nice to hear that you've probably still got a warranty despite your mods ....
