This 2A3 schematic shows the same 717A operating conditions that Yamamoto use for their 717A/45 SET.http://www.audiohobbyist.com/images/7172A3/7172A3sch.jpg
The 45 is biased at around -50V so driving a KT88 should pose no problems.
The 6SJ7 can be a very good driver for pentodes, so I wouldn't necessarily assume that something more exotic will sound any better.
