Or maybe this Tung Sol is good?
This is a Seimens und Halske Valvo from the Munich factory, not the Seimens Valvo from the Hamburg factory which basically is a rebranded telefunken. The added air and low end is definitely there - the mids just aren't doing it for me at all for my application, and I've tried it with different mics. You can tell it's a quality tube, though.
