A schematic is always nice but it seems easy to follow. The ground cap leads might be a pain to solder without thermal reliefs around the pins

here is the schematic my torrids have (2) secondaries and can run 15 volts or 30 volts per rail depending on how you connect them got these for 10 bucks apiece later i might go to higher volt torrids . will post the double sided pcb for a bridged lm4780 i made

i love it when you dont get smoke! works fine, ran into a little tight space problem at the 4k7 2w resistors so i drilled 2 holes in the center of the ground plane, so much for planning ahead.tilted the recs back for clearance 1 pic explains it all!
