I put 6146Bs in my B&W5100B and reneutralized it.  It works just fine and 
have not had problems.  Remember most manuals say to redo the neutralization 
when changing finals anyway.

On radios with no neutralization that is different.  The DX 100 can be 
modified to add neutralization, the Valiants have it.  Don't know about any 
others but it shouldn't be a great problem to add..
