Yes, this is possible.
To make 2 LM317 circuits. Identical.
And then you stack them one on top of each other.
One for the positive half
and one for the negative half.
One hook only:
You have to use Transformer with 2 Separate windings!
( one with a common middlepoint for Ground, will not work )
So make sure you buy 2 x 12 Volt trafo. Or what voltage you will use.

I got two of them.
An externally hosted image should be here but it was not working when we last tested it.
The idea is like this. This is for higher current (LM338).
For preamplifiers and currents max like 1 Ampere we use LM317.

You don't want super low impedence caps at the output, at the contrary.
Read the serie "using 3 pins regulators" on this website: http://www.acoustica.org.uk/ You can also find more reference on this forum doing a quick search.
