mesa tube question

[Cowbell Fever]

I have four brand new Solvtec el-84's that Carvin sent me for my V16. I understand Mesa only wants you to use their tubes. I understand they use sovtecs too.
When the time comes for me to replace the two el84's in my express 5.25 can I just plug a set of these in(aside from warrenty issues) or should I order some from Mesa? (I want to have extras on hand)

Get the GT EL34-S's They are relabled JJ's. #4-#7 rating and you'll be OK. You won't void your warranty with this rating.

Thank you for the advice. I guess I will order a set of el-84's from Mesa on Monday, then I have no worries.

However, I have a few different 12ax7's (jj's, ge, sylvania, sovtech) that I am going to swap out at will 8) just as soom as I figure out which pre-amp tube is V1!

V1 is normally located nearest your guitar input jack
