The unit clearly says 12AX7 and that's what you should use. There are several good varieties being produced currently. The Sovtek 12AX7LPS is clean and quiet. The "reissue" long plate Mullard has some of the famous midrange accent. The "reissue" TungSol will give you a dose of NJ "chime". Select a variety based on the "tone" you want.
All 3 of the above are made by New Sensor at their Saratov, Russia, plant.
