Modwright SWL9.0 SE Tube Rolling


I'm using TungSol 5687 tubes as supplied by Modwright in my SWL9.0SE. They are very linear and extended with deep bass, however they have little midrange bloom.

Has anyone rolled other tubes in the SWL9.0SE? If so, would you please describe their tonal characteristics?

Dennis, I tried the RCA 5687 bronze plates, not on the preamp, but on a Modwright 999ES cdp. They sounded veiled and lifeless compared to the ones above. Maybe it was the tubes?
Can anyone recommend a source/s for the GE JAN 7044s? I had a bit of a troll around and didn't find any readily available.

Thanks
thanks 1markr. So, is this the correct tube number for the Sylvania GB65687? just wanted to make sure that wasn't a typo. I'll keep my eye out for GE 7044. The GE's I'm hoping to try are the 5 star 5687.
