The DB23 from RME and the Cosmophone-35 use the 6J6 which was developed as a low noise VHF/UHF dual triode....  I'm sure there are others as good if not better but those work pretty good....

Hi,  Maybe you can save me some time researching.  I'm looking for a  
twin-triode, low-noise vacuum tube for building a RF amplifier.  I  
have been looking at the article "The S-9er" and thought I would try  
the same but in a cascode configuration and see how it works in my  
SX-28A.  What tubes would you consider?  Thanks.
