Looks perfect.

Well, that's it then :-)
By the way, I'll go for the solution with two bridges per channel.

Great support in this forum !

Please find attached ZIP file with schematics and pcb-layout for PSU with MUR860 diodes and bypass 4,7uF caps, which a friend of mine was so kind to make for me.

This really nice work, I believe, and I just cannot wait to get started making these pcb's.

Each pcb is for two channels. The layout in the PDF file is scale 1:1 when printing it out.
Hope someone can make use of it.

We were very much impressed with the picture of bridge pcb posted on 11-23-2003. i will like to know which software u used to draw the same. Waiting for ur reply

Can someone please explain to me how a single diode bridge feeding from a center tapped transformer could somehow result in 50 Hz ripple?
I have been seeing this statement repeated ever so often, but has anyone actually bothered to simulate this in PSPICE? Or even better, actually put a 'scope across the capacitors?

It does make some sense to use separate bridges if the windings supply voltages that differ substantially, as could reasonably be the case if you're using two diffferent transformers, but from a single? I doubt it...

Having separate bridges for each channel is probably a good idea, though.
