<No Jim,

<A PP RF amplifier does not need LP filters if using pi-net output circuitry.

##  Im  talking  about a PP  SS  RF  amp.....  like  ur  typ 1.5 kw  SS  amp....or  xcvr. 





<And a GG amplifier running class B does not generate key clicks, my main amp
<is running ZERO bias class B for more then 40 years in CW and SSB.

##  any  high Mu  GG triode  operating  with  ZERO  BIAS  will  draw LOADS of
idle  current....  and  is  operating  class  AB2. 

##  Increase  bias  voltage,  till idle  current  drops  to  0-5  ma....  and  u  will  get  key  clix,
try it yourself.
