Default Synthesizer Power supply

I am working on a Yamaha CS15 synth. I need to repair or replace the power supply. I do not know my actual requirements but it has an A/C consumption of 110V/12W. The output voltage is +15/-15 and I am guessing about 1 or two amps. In order to repair mine, I will need one regulator I.C, two transistors and two tantalum caps. Any suggestions for a more modern yet economical circuit? Prior to my regulator stage I have +29Volts and -29Volts.
