First connect both secondaries in parallel, i.e. connect dot to dot, CT to CT and non-dot to non-dot. Then connect the rectifier's 1st ~ terminal to the dotted secondary terminal and the 2nd one to the non-dotted one. Connect both electrolytics in series, as you've done it yet. Connect the jumper between both 'lytics to the CT's, connect the rectifire's + terminal to the upper 'lytic's + terminal and the rectifier's - terminal to the lower 'lytic's - terminal. Thus the + terminals will show +35 Vdc at idle and the - terminals will show -35 Vdc wrt CT/jumper.
