Tube rolling CJ MV60SE

Looking for tube rolling recommendations for CJ MV60SE amp that I am using with VTL 2.5 preamp.

If it can handle KT88s, not sure why it couldn't, but check with CJ - the Genalex Reissues are very, very good. I would get them from Jim McShane who has a reputation for being a good tester and has reasonable prices.
