No Jim,

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

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.

##  GG  triodes cant  be used  In  class  B  on  CW.... u  will  get  key
clix. 
A  simple PI  net  will kill  even  and  odd  harmonics.   Typ P-P  Ham
xcvr
requires  7 x LP  filters  to  kill  even +  odd  harmonics.  GG  triode
does 
not  require a  LP  filter.....none.
