aleph 5 with brian gt boards

Thanks.
I just have doubts in R12, R13 and R17 whose values should be different from Aleph 30. Also on the bill of materials of aleph 30 reported that the R49 is used for higher power designs - not shown on layouts, stacks over R23-26.
Just one more doubt, can I use in C1 and C3 Capacitors Nichicon (Fine Gold) UFG1H221MHM1TO CAP ALUM 220UF 20% 50V RADIAL and in C2 Elna (Silmic) CAP ALUM 220UF 20% 35V RADIAL? The voltage is different
