I'm no tube expert, but I use Telefunken Black Diamond tubes (made by JJ) in my C2300 with good results. Before that it was JJ Hi-Performance Gold Pin tubes. The BDs have a good dynamic and frequency balance, and to my ears pretty neutral; the JJs are weighted toward the mid/low end and warm. Smooth on top with no harsh highs.

FWIW, Magnum Dynalab uses JJ tubes (6922s) in their tuners; I don't know which tube though.
