Got a new Recto, it is the version before the switchable 50/100 watt model. It has MESA STR 430 which i believe are the Sovtek 6L6WXT.
I have older Marshall & bias my own amps but am a noob when it comes to MESA tubes.
I like the Tungsol 6L6. Does MESA make those or can i just buy a non-MESA matched quad for my Recto ?
