It's normal that a transformer rated at a certain output voltage will actually put out 15% to 20% loaded or unloaded.So 18x1.2= 21.6 VACafter full wave rectification21.6VAC x 1.414 = 30.54 VDCAre you using Heatsinks like Ruud said?You have to use good heatsinks with thermal paste compound on the regulators.

after full wave rectification
21.6VAC x 1.414 = 30.54 VDC
