I think if you dig up shcematics for the Pass X-Bosoz psu it could be easily modified. (Look in the 'my take on x-bosoz' thread) I'd bet all you'd have to do is replace whatever is in the zener stack of the existing schem with a stack of 2 x 9.1v zeners (plus AND minus rails) you'd end up at just about +-15v. You could also lower the voltages of all the caps making the whole thing cheaper and smaller than a Bosoz PSU. Use maybe a 15v dual sec. traffo?
