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?

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.

Hi Dennis,

The first "6" shouldn't be there. It should read Sylvania Gold Brand GB-5687. I have the gold pin versions. I also have a pair of the 5-star GE 5687s, but have not had a chance to try them yet.
