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...

That video is hilarious, and also...Edwin Howard Armstrong's story is really interesting although tragic.

I think the consensus is that KT120s will work in a 502P, and not set your cat on fire...I'm off to melt some sand.
Deforest, Edison, Fleming, then Garcia.
Excellent, I can envision that.
Just please use domestic instead of purchasing from the Saudis.
I think you just make a glass bulb and stick some wire in it...I plan to suck the air out with my vacuum cleaner or merely place the thing in range of a Lana Del Ray song...this should work...
