I used a 3A, over-voltage, over-load and surge-protected one from Element14 http://au.element14.com/xp-power/ecl15us05-t/psu-15w-5v-mini-chassis-mount/dp/1337088 It's (too) pricey, but did the job nicely. I wrote up the whole business on C128.com http://c128.com/comment/539#comment-539 > Again: You need to work on 230V for this, don't, unless you know what > you're doing. Indeed.
