Yes a 5814 is a direct replacement for a 12au7. As a matter of fact I use GE 5814 tubes in my phono preamp.
You can also use a 5963 and a 6189.

5814 tube for Audiomat Solfege Reference?
I'd like to try 5814's in place of the 12au7's in the Solfege, but I don't know if it will work. Does anyone know? The research I've done states that the 5814 is a direct substitute for the 12au7 IF the tubes use a "parallel filament circuit." Does the Solfege? Is there a way for me to figure it out?
Thanks very much!
