I have a Squeezebox Touch and two Abrahamsen A-dac usb D/A converters that I'd like to build decent power supplies for. Just as an experiment to see if they'll sound better. (...And just because it's fun, of course.)

The D/A converters have 24V DC 0.5A wall warts, and the Squeezebox has a 5V DC 3A wall wart.

I'm looking for PCB's or preferably complete kits for good power supplies to replace these. I need transformers with primary windings for 230VAC european power grids (in Norway).

The best would be kits that I could use for both these applications. (With different transformers, of course).

I've built a couple of TREAD and STEPS supplies on PCBs from www.tangentsoft.net, but sadly these are no longer available. Neither are his newer YJPS pcb.

Where should I look?

All tips and pointers will be greatly appreciated.

Thanks!

I ordered three σ11 boards and the parts AMB has for it in his webshop. Looks good for this application, I think.
 
Now to figure out what transformers, enclosures and other small parts I need.
