since the old psu's transformer went quite hot, I opted for a bigger psu: 30VA, Pri 230Vac / Sek 2 x 25Vac, 0.6A. 8xMUR160 bypassed with small filmcaps,
then smoothed by 4x 4700µF electrolytics, preregulated with IRF530/9530 and finally fed into ordered superteddyregs for +24/-24 output.
starground made after the regs. relocated groundloopbreaker at the top next to the powercon.
