Hi all,

I am wishing to build a replacement transformer for my Cambridge Audio
DacMagic DAC (the new one that's just come out). I am unhappy with the
original PSU because it is inefficient and doesn't have a physical
on/off switch so it's constantly drawing a current unless you unplug it,
and I like to save evergy where I can.

So I was wondering whether I could build a new transformer for it based
around a toroidal core transformer, in the hope that it will reduce
power consumption and, if I'm lucky, make the DAC sound better.

Would something like this do?

The power input on the DAC requires 1.5 amps AC.

What else would I need, other than a circuit board, a rocker switch and
some kind of housing? Or should I just give up on the idea and stop
wasting my time?

Any advice is appreciated, my electronics knowledge is GCSE standard
(i.e. not very good).

Thanks in advance,

Anton
