[Boatanchors] [Boat anchors] 6146 Variants in Viking Valiant

[Glen Zook]

Use the 6939 tubes if you want to convert the Valiant to run about 40-watts!

That tube is a dual tetrode designed for low power UHF operation!

Methinks he means the 6293 which is a pulse rated 6146 with a peak rating of 1000-watts input.  Those make for excellent replacements for the 6146 and 6146A/8298.  

Be careful if you get the 6146B/8298A or 6146W tubes.  Those are harder to neutralize than the original 6146, 6146A/8298, and 6293 tubes.

Not sure what tube OP was referring to.

Might take more than a pair however.  Valiant uses -3- 6146's in final and
-2- in modulator.  8298's work real well.
