Ed, W3NR asked,

"I need some help with the tuned input for 4 811A's..."

Ed,

Presuming the total input Z is about 60 ohms, then the values are as
follows (Q=2):


160M        C1:  3300      C2:   3100   L:   3.53

80M                   1700               1670          1.90

40M                  900                    840            0.96

20M                  440                     417            0.47

15M                   300                    275             0.32

10M                    220                    205             0.23

This is a pi-net and C1 is the coax input, C2 is the cath. I use fixed L
and nice 'big' trimmer caps
