Hi,
post 21 works.
it needs a 15+15Vac 2A transformer (60VA), but this will not power a chipamp particularly well. Peak current ability is lacking.
post 22 works. But look at the ripple, 1Vpp, for an output current of 0.1A. Again this cannot run a chipamp.
Just go and buy the correct transformer. If you are patient you may pick up a bargain.

I don't want to push my own stuff, but I am not makeing a profit, so I guess it can be forgiven. Follw the link below my post and look for the Universal PSU in the catalog. It is about $9.99, allready have the components silkscreened, so you just have to populate it.
These boards are from the DX amp groupbuy, I had some extras made.... This will give you all the regulation you need based on a C-L-C filter and can accept caps up to 35mm in diameter.. well 37 if you don't mind them very close... Pads are finnished in Sterling silver.

Both of circuits have disadvantages.doomsweek said:
The stabilized - because of useless additional power dissipation.
The second - because of unsimetrical positive/negative supply. The negative cannot deliver the same current. But if you use bigger condensers, it's possible to lower the difference in loadability.
