Two things to note:
1> In other threads, the power tubes have been mixed for years, with practitioners stating you 'get' the best attributes of both tubes.
2> The NOS FDD20 develops super DEEP bass and retains it's treble magic. But it takes at least 150 hours. plus, of use, before the bass matures. You'll likely hear it starting to deepen at 50, then more by 100, more again by 150 and 'endless cavern' at around 200 hours.
