I have had good luck with JJ EL34 type 1. Sound great.
Mullard EL34 that sounds best
Will need a matched quad of EL34 for the VAC Avatar SE integrated at some point. Currently using Svetlana SEDs but I guess Mullard should be better.
What particular Mullard would you recommend and why ?
I use Mullard 12AX7 longplates in preamp and RCA blackplates as driver tubes.
