Default ESP P68 500W - parts values

I am planning to build this amp from Rod Elliot,
http://sound.westhost.com/project68.htm using 70V supply.

Just want to confirm that I got the values correct,especially for R16.. 17, R18...R27
Did anybody else build it?

I am just beginging to build this amp from Rod Elliot's project 68, what is the appropriate value for the wirewound resistors R16, R17... R21? And what is their purpose I know I read it somewhere but can't remember, something to do with leading current? Also one more thing, what should the voltage rating of C4 and C5 be? I know C13 and C12 should be at least 100V DC, but I only bought 2 of those. Thank you for your time.

Petar
