Looking for brighter tubes


Attention tube heads: I'm looking for brighter (more treble...not higher amounts of glow and chrome) tubes, if they exist. My amp (Jolida JD502P) has a well regarded bunch of Russian Tung Sol 6550s and 12AX7/12AT7s but I'm wondering if there's anything out there that imparts more sizzle in this amp. I do like the amp as it is...but hey..."rolling rolling rolling, keep them tubeys rolling...

I was wondering the same thing about the TS KT120's Myself. I haven't stumbled across any specific info on the Jolida on the web though. I have read that the KT90's tend to have a more solid state sound and less of that tube warmth. I am sure someone will let me know if I am wrong.

Yes, that's my experience with the EAR 890.
In a phone conversation about 10 minutes ago, Mike Allen of Jolida told me that KT120s should work fine in my (newer version) JD502P. So there. Also, he seems like a cool guy.
i use tube guitar amps and have found that a good Chinese pretube adds treble and edge to my sound.... the russian stuff is more rounder sounding
