[sdiy] digisound power supply

[ian taylor]

Hi all, im sure you come across power supply issues again and again...

I have around 30 digisound modules and a keyboard that need power,
looks like my original digisound supply has given up so im looking for a replacement.
I've seen a couple of people who have used power one and motm supplies,
so maybe one of those will do the job?
(the motm tripple supply looks good but im not sure its powerful enough to drive all my modules)
I'm really not confident enough to rebuild my existing supply although I do have the 1A version.

I need +/- 15 volts ideally about 1 amp per rail so all the modules can be powered,
plus a separate +5 volt supply for the alphadac controller.
The board inside the keyboard does have an output for 5 volts, but according to the literature I need a separate one,
I have no idea how much current the alphadac needs but obviously more than the keyboard board provides.
I do have a separate little power supply board to provide 5 volts from 10~15 volts ac,
which I was hoping would give me the extra 5 volts from the main supply, rather than use 2 separate ones,
here's a link to the item: http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=160413173496  

Does anyone have experience with powering this system? And specifically the keyboard/alphadac combination?
Or any ideas whats best to go for?
I'm in the UK so would prefer to source it here, 
regardless I need to power up the system so I don't mind getting one shipped in.

Cheers.
