Ray, I finished the circut and ended up with 574v on the plates and 509v at the last leg of the B+ rail. IT blew a 22uf 450v cap that I had in ther the others being 500v at the tail end and 4 50uf 350v in series and pairs good for 25uf at 700v. I only used a 1K 5W resistor in place of the choke, I'm going to order a pair of chokes for this one and the other for somthing else.I am thinking of a 50v 50W reverse zener to drop B+ a little more. By the way the amp does sound great biased at 21ma. Thank you DonJ
