Looking for voltage regulator

Hello

I'm looking for schematic good but simply(max. 6 transistors per rail) discrete (BTJ) voltage regulator for my headphone amp

What I need?
Vout= +/- 15-18V
Imax=800mA -1A
BTJ transistors
My idea is:
Trafo=>rectifer=>capacitors=>regulator=>Kmultiplier=>headamp


Thanx

Be aware that a cap multiplier largely undoes some of the advantages of the regulator, like low output impedance and tight regulation.
