Just a thought ... has anyone done
any calculations on the values for
a Pi-Network ?

I expect you will be surprised.

##  1800 divided by  472 = 3.81    
All the values  for C1, C2, L1  will be  3.81 times bigger than what ever you are using now for 160m amp, assuming
same tubes, same po, etc. 

##  3500 divided by 472 =   7.42      Take ur existing  80m amp values.... and multiply by 7.42 

##  U can use GM3SEKs  excellent free PI  or PI-L  software..and plug in the plate current, loaded B+  etc....and it will
spit out the tank values for any loaded Q  you want.
