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.
