Help is appreciated. Thanks!

That output could be 24 x 1.414 = 33.93v If you want the output around 24v, you have to find a 18v ac transformer. This is a typical AC to DC layout. http://www.eleccircuit.com/wp-content/uploads/2009/11/simple-ac-to-dc-converter-9vac-to-35vdc.jpg For 9v Regulated output, you can use a voltage regulator like 7809 in series with source of 24v. **broken link removed**

Since it was not listed in the condition. Click to expand... That can't be right. I'm sure it's not okay if the 24V output actually outputs 18V.
