Does it actually work at all? I really don't see how you could subject an LM317 to these voltages. How could you send AC straight through a 10mH inductor? What happens if you put 100uF straight over AC? Where does the DC come from? Etc.
I must be in full design review mode... Occupational hazard, I guess.
Looking at the schematic further, my comment above on C4 also applies to C3 and C6. C6 is running right at its rated limit, and C3 is likely seeing a voltage above its rated limit sitting at the input to the LM317.
I would definitely use higher voltage rated caps for both of these - you risk blowing the caps as the applied voltage is going to stress them over time.
OK, just a few more things to chew on - good luck with the supply, hope you get 'er running happily and can move on to other parts of the design.
