I know that the popular mantra is SMPS, but I still use linear regulators. Here is my version of a multiple voltage regulated supply. It's not efficient, but it works, it's adaptable, and it's not noisy.

 

I use linears when I can tolerate the wasted power and heat. Any application above 20 - 30W, they are not practical.

 

Nice layout. I'm sure you're aware that the 15V regulator has to carry ALL the load currents of all 4 regulators.

 

I also designed the positive and negtive power about 20 years ago.
It's similar as you did, but I seperated 5V for TTL and CMOS or other 5V circuits, and the ±9V,±10V,±12V,±15V are for the Op Amps.

I'm' not translate yet, but you can see it through google translation.
Only the circuit and Boards you should care.

Thank you. Yes, I don't really expect to use the regulators in this configuration, but if I do something similar, I'll keep that in mind. There is room for a small heat sink on the LMxx's.

I have some 79xx regulators, but I haven't had a need for them yet. I like your PS.
