[Hallicrafters] 5894 Tube for the HA-6 Transverter

[jeremy-ca]

Nothing peculiar about it; just some smart engineering that leaves amplifier 
designers more mounting options. The orientation prevents filament sag into 
the grid. Take a look at a 30L1 also.

The 809, 811, 812 and some others have the same requirement.
