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!

Andy at Vintage Tube Services will fix you up. Best to talk to him, as he will recommend options to suit your particular system & preferences. Tel # is:

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.
