Mark IV/2:50 tube question

[bloodbath666]

My boogie 2:50 power amp had a tube wear out in it. Can I used the mesa boogie tubes from my mark IV in the 2:50? I have some JJ's that were matched for the 2:50 and Bob at eurotubes said they would work with the mark IV just fine, so I'm wondering if this is the same for the mesa tubes?

you can use the tubes from the mark in the 2:50, make sure that the bias on both amps are set correct for the tubes you are going to install

the jj tubes in your mark will make your sound better
i installed 2 jj tubes in my dc5, realy fattened my tone
