Hello all. As NOS tubes get rarer and more expensive, I've been thinking that there is going to be a point where I'm going to have to start looking at new production tubes for replacements. Has anyone tried any newer production tubes that they felt were as good or close to the better NOS tubes out there? I'm especially interested in 6922, 12ax7, 12au7, and EL34 types or variants. I'm also especially fond of the classic Mullard, Amperex, or Dutch Phillips sound. To me the only newer tube that I found that is comparable to NOS tubes is the Winged C EL34. I'm sure hoping there are others. Any thoughts, opinions, and experiences out there with this are greatly appreciated.
