RE: Ugly, it's a good thing you asked ahead of time

?? Does it have another transformer on the inside? 12 VAC will only get you about 18 VDC off of the first cap (1.414 * VAC = VDC) and so, to get 18 V regulated, it is not a normal regulator as it could be a low offset regulator and then how does it get -18v DC? Gasp, it could be a switching regulator??? Those are VERY bad.

Anyway, as I explained, a 1 Amp, 24 volt center-tapped transformer and very simple fixed voltage regulators and reasonable capacitor size, 3300 uF, 50V or so (I'm trying to recall) should get you to a pretty good power supply without having to go to the Belleson's. EBay will sell you regulators for $8 each. I tore up an old CD player and broke off the power supply section for mine. The circuits are really simple if you know how to use a soldering iron. The transformer is the most costly item for this and, probably, why you have to spend big bucks to get reasonable performance.
