I disagree with you, I do not think the graphs are similar.
But the graphs, and " maximum swing analysis " are NOT the sole reason to use, or discard, any tube. There are other factors one must weigh. The less-linear graphs I see, won't stop me in my intended use of the tube, one time in my audio chain.
In what gear were you employing the tube, preamp or amp, may I ask you ??
How many stages, one, or more in series??
Aside from microphonics, how did it compare to a 12AX7 sonically-speaking, in your circuit, and from your direct experience ??
Thanks in advance.
