Hi Simon,


If you'd asked a fortnight ago, I could have helped - I've just sold one!

I suppose the good news is that it's a fairly common part - what
you're looking for is a CPS150 power supply, which is used on many
of the soundcraft mid-range desks; it's definitely used on the Delta
range (which was the one I sold).

These are not uncommon in the sound hire business, and many companies
will carry a spare - might be worth phoning your local hire companies
to see if they have a CPS150.

If all else fails, it's just a simple 17-0-17 linear supply (1.25
amps per rail) with an additional 48V purely for phantom power.
That's fairly common for mixers, so it may be possible to bodge up
something from another mixer. The connector is quite unusual -
Soundcraft sell it for 27 pounds +VAT+postage, but it's a Hirose
JR13 - available from RS for 3 pounds for the chassis connector, 7
for the cable-mount one. Part numbers 454-025, -031, -003 and -019


The circuit diagram and service manual for your broken power supply
is on

It's a linear supply, so should be relatively easy to repair.
