Tube for Sonic Frontiers SFL-1

Would like to try and get a more "tubelike" sound from a Sonic Frontiers SFL-1 pre. Richer midrange,more lush overall, if possible. Uses a single 12AT7A type tube. I'm pretty new to tubes so any suggestions would be most welcome!

Thanks FP, I'll give them a look...

I was using the SFL-1 before I got the Line 1 I am now using. In the SFL-1 I have a Mullard 6201 tube. It was supplied with the unit when new. The 6201 number is off the tube box cover. It has a nice warm sound. If you want a lot of bloom check out Mullard tubes.
