[Boatanchors] 6146 vs. 6146A vs. 6146B or 6146W and Grid Current

[manualman at juno.com]

Generally, adjusting grid current should not used for tweaking RF output.
Grid current set to low below the manufacturer's recommended operating
value, generally can produce distortion of the RF output signal. Of
course, some hams consider all SSB to be nothing but distortion
regardless of any settings.
