The older Blacet supply I think has a couple trim pots inside for adjusting
the voltage.  I had one, but sold it.  You could email Blacet and check but I
think its a fairly common LM723 regulator circuit.  On the common PowerOne
supplies which are also LM723 based, for 12v operation you lift or change a
couple resistors.  They even print the instructions on the case.

Its inefficient to use a second regulator, especially as it sounds like you
dont *need* the +-15v any more.  It really should be a trivial change to make
it truly +-12.
