[sdiy] synth power supply

[Derek Holzer]

New thread for a slightly different question, related to how much EMI 
can a power supply give.

I'd like to build a new Doepfer case for less than the EUR 350 they 
charge for a new one. And the DIY power supply kit they provide uses a 
15VAC 2.5A external wall wart which then gets rectified and regulated by 
their DIY PS unit in the case, which I would like to avoid unless 
necessary. I'd rather not mess with 220V myself, so I was looking at the 
following power supply:

(Sorry, German only...)

Mouser:

But I have no idea how much EMI this might introduce into a small flight 
case with modules mounted next to the PS. Doepfer use a very large ring 
transformer which they say is quite clean. How would a PS like this 
stack up against theirs?

What other options would people recommend, keeping in mind that I don't 
feel "qualified" to wire 220V?

best,
Derek
