Who makes Mesa Boogie tubes?

[Tuned]

to MESA/Boogie:

special thanks for chiming in. I'm actually the topic starter and am still in search for the tubes fr my Black Stripe Mark III.
As I am in Russia I 'd rather get matched Sovteks or Svetlanas noticeably cheaper in this country than re-import them back here. The question is, where the technical requirements line lies.
EDIT: However, your links don't work, I checked twice.

Thanks to all that added personal experience. Always good to know what the actual players perceive.
I'd love to hear what different tubes add to your sound

Last I heard, all Mesa tubes are JJ's. Before that was Ruby, sovtek, etc. Seems to change quite often so it's almost anyone's guess. I do prefer buying Mesa tubes if I'm in a pinch though.

Ruby are rebranded tubes made by an assortment of other companies if I recall correctly. Probably sovtek and tung sol and stuff.

As I said above, we select tubes from all 3 of the worlds tube manufacturers. We select the tubes that sound the best and are the most reliable - then we run them through a battery of tests and select only the best tubes. Our 12AX7s are currently manufactured by JJ. As the largest consumer of 6L6s and 12AX7s we get first choice of tubes - what we reject goes on to other tube re-sellers.

Good to know. I always buy Mesa tubes
