I replaced my dead transformer in my OB-Sx with two toroids, one for the +/-15V and one for the +/-5V. Fitted nicely (in the OB-Sx) and doesn't hum like the original used to do. I ditched the voltage selector switch on the back and added an rear mounted fuse holder. Supply voltage can still be selected by moving wires around on the Wago block I added to neatly and safely distribute the mains to both transformers. http://www.muffwiggler.com/forum/userpix2/650_wp_20180605_16_06_51_pro_1.jpg It's not as easy as using a direct replacement but it's another option if you don't mind a bit of hacking and are happy with mains wiring.
