They are flash tested as part of the certification agreement."

I agree with Graham. His company is holding all the electrical safety responsibility.
Flash testing ensures a unit is safe.

In my opinion a novice making this power supply could easily make something lethal. I have had plenty of 230V AC shocks in my life, and I am aware that one day one could kill me. I try to avoid contact with the mains! You should too (here I am referring to all who have asked).

A death could easily happen to a constructor, and it would not matter if I printed a disclaimer, I would be had up for manslaughter. Ever heard of those accident solicitors?

I am sorry, I will never sell any mains item as a kit.

Other manufacturers are not as accountable.

Such a kit would be a very good learning exercise for me Graham. Thumbs Up I might check out some of your kits in the future although I do worry that I could wreck some of my electronics if I make a mistake.

I too would be interested in a DIY kit.

Agreed. The PSU1 gives a very clean low noise supply and makes a positive difference on every GSP unit I have owned. I have seen the transformer inside my PSU1 and it is a very high quality unit, not cheaply acquired or substituted.
 
I did the same thing as you with the DACMagic I had with a big linear (transformer) PSU to replace the AC wall wart. Fuller and clearer sound from the unit.
 
Better (low noise) regulation and capacitors have improved my digital sound from the Squeezebox Touch I use. The EDO and Toolbox mods helped a lot, well worth investigating if you have a compatible Squeezebox.

Never underestimate how important a good supply is.  There is a lot of truth in the adage "Amplifiers simply modulate the power supply."  

I have a Cambridge Dac Magic, which comes with an AC wall wart, which is simply a crummy transformer in a plastic case.  I replaced it with an Avel 30VA toroid, and the results were significant.  Sound images became far more specific, dynamics improved, and the whole music gained a foundation that was not there with the stock wall wart.  Any decent piece of gear can benefit from an upgrade from a wall wart to a real power supply.

I doubt it Wink

We in the USA are free to bitch about the Postal Service and do so at every opportunity.  We also have effective competition in the form of UPS and FedEx.

Brazil is one of my all time favorite films, a true classic.
