TIME TO RETUBE MY 400+........

[2-STICKS]

WELL, AFTER SERVING ME MERCILESSLY FOR 10 YEARS OF HARD SERVICE, MY HEAD IS FINALLY REQUIRING A RETUBE. THE LAST TUBES I HAD INSTALLED ARE ALL MESA..........THE 6L6'S ALL HAVE A GREEN/YELLOW CODE ON THE BOTTOM BAND..........DOES ANYBODY KNOW WHAT THAT DESIGNATION IS ALL ABOUT?

I HAVE RETUBED MY GUITAR RIG ON SEVERAL OCCASIONS, AND HAVE FOUND JJ'S TO BE MY FAVORITE IN THAT APPLICATION. ANYONE TRIED JJ'S IN A 400+ ?

ANYBODY HAVE ANY OTHER SUGGESTIONS?

I AM NOT LOOKING TO CHANGE MY TONE.......I JUST WANT TO GET THAT CRUSHING HEADROOM BACK.

I recently retubed my Buster Bass with JJ's and the sound is tremendous. Lots of headroom.
