I'll second John's recomendation. However, the turn-on voltage transient is fairly well documented with that design and its predecessors. I'll go one last step further and suggesting a call to the tech support of your SS amp maker and see if a short duration spike 40-60V high would be any threat.and then there is the sonic side to the topic. I suggest you'll like a good tube pre. tubes properly done are(so far) unbeatable in my experience.
cheers,
