If you have a list of the cap values in the PSU, could you post it here? I have been thinking of recapping mine some day.
Commodore KIM-1, PET-2001, CBM 8032, CBM 8050, CBM 8250LP, D9060, VIC-20, C64, C64c, 1541, 1541-II, 1571, 1581,
Amiga A1000, A1060 Sidecar, A500, CDTV, CD32, 1084S, A1200, A1200 Magic Pack from Petro, ex-custom-case A3000T (now a complete A3000T), repaired A4000T and looking for more :)

I have to get some time to triple-check this, but I believe this is correct for all of the electrolytic capacitors on a 110v NTSC Amiga 1000 Power Supply:

C11     2200uF  16V     
C12     2200uF  16V     
C13     2200uF  16V     

C15     100uF   25v     
C17     100uF   25v     
C19     100uF   25v     

C50     470uF   220V

C09     4.7uF   50v     
C10     1uF     50v     
C16     470uF   35v     
C18     330uF   35v
C49     10uF    85v     

I finally got around re-capping my A1000. Here is the caps list for the 220v PAL Amiga 1000 power supply:

3x 2200uF 10v
470uF 35v
330uF 25v
3x 100uF 25v
10uF 35v
4,7uF 50v
1uF 50v

I did not replace the big mains cap C50 as I couldn't find close enough replacement. The original in my PSU was 180uF 400v or there abouts. I believe that cap is not in a stressed position and as the smaller caps measured very good after removal, I was happy to leave the big one there for now.
