Phono pre amp

Hi all,

Would a 6an4 be a good candidate for service in a phono preamp?

Just thinking about it and wondering what some opinions would be?

Thanks,
Nick

mu, gm, and input capacitance all seem decent. The curves, if they are accurate, do not look particularly linear. Also, for comparable gain it requires a lot more voltage (and about the same current) as a trioded 6GK5.

Well it was just a though. I think I'll stick with my other idea.

Thanks
