Favorite tubes for Mesa M-Pulse 600?

[nosajwp]

Broke one of the tubes in my newly aquired Venture (don't ask how), and was wondering what you guys have had success with in the Mesa M-Pulse 600.

I always had good luck with JJ's in my guitar amps, but would love opinions for the Mesa.

I've just been using the Mesa branded tubes in mine...

Mesa makes a high quality 12AX7 replacement tube which is terrific. They are $20 each which is steep for a single preamp tube, but they last a long time and sound great.

Anyone else?
