It works - well, eventually. I had a senior moment while laying out the PCB, but a little bit of IC leg bending fixes the problem.

"It's a power supply and it's on my bench. That makes it a bench power supply." — I honestly LOLed.
Wow. Just wow…
Use a PROPER PSU
you need a Looooooooooooooooong holiday
dual 741 ???????????????????????????
that makes it a bench power supply…………..so much for British humour. Can I watch Dave Allan now?
plus and minus 12V, so 24VDC ???
Question: Is it best (More efficient) to Buck to 3.3volts from say 4 AA's NiMH , or Boost to 3.3v from 2 AA's NiMH twice, what gives you more run time. (being as you have one of those silly scope thingies).
Nice work in fixing your design Julian. Crossed over legs? Im sure its all in the best possible taste! 😉

waste of time and space.
Mr Ilett . please check Facebook.thx.

Love your projects but PLEASE invest in your audio delivery

One thing I noticed which may help reduce the hum is a ground flood. If you flood the top and bottom and stitch them together with vias this will vastly improve the sound quality.
Seriously comical, Julian.
