: : Can anyone tell me if I can replace a 12AX7 tube with a 12AU7 without any concern ?
: You should have no problems if thats the pre-amp tube in a guitar amp. The amplification factor on the 12AX7 is 100% the factor on the 12 AU7 is 17% this will allow you to turn up the volume with somewhat less feedback and it should not hurt the amp. Great for harmonica not so great for guitar. Good Luck..
:Thanks for the reply, Bluz. I'm using it in a mic preamp that I run into a PA so this should help.
