[ARC5] The 6U8 - what's the big deal with this "toob"

[Kenneth G. Gordon]

The 6GH8A is also a plug-in replacement for the 6U8/6EA8, but the pentode 
section has greater transconductance than either of the others' do. The 
triode sections of all three appear to be identical.

I routinely use the 6GH8A as V-1 in the HW/SB transceivers when the mic. I 
am using has low gain.

I would be curious to learn if the 6GH8A would work in the Collins rigs as the 
tone oscillator in place of the 6U8.

Probably not.
