I'm installing the tubes4hifi 12AU7 driver boards in a pair of Dynaco MkIIIs for someone, and we need to choose the output tubes.

He describes his listening tastes as 80% Classical and 20% Dave Brubeck style jazz. Speakers are Sansui SP-3500. And he is older, which may have some bearing on perception of higher frequencies. I doubt the amps will be pushed hard. Preamp is a Marantz 7T that was reportedly completely serviced a few years ago, with some new electrolytics installed.

The budget limits us to current production types.

Suggestions for system synergy?
