I'm gonna retube my mesa dual rec pretty soon, and am wondering what you guys have tried in these things or in your other amps? I ran 6l6's in my jcm900 and liked the tung sol's, but liked the sovtek's WXT+'s better. Good price too, I thought. I already have an EL34 amp so looking to stick with 6L6. The amp is not used for power amp breakup so I know choice of tubes is less critical, but just interested in some direction from you guys.
