I used a 6" piece of home made 30Ohm coax from the tubes to the matching network. The pi network was 100pF trimmer on the input side, a 40pF trimmer on the output side and an aprox .16uH coil.

I am converting a previously-modified SB-220 to a 6 meter-only amp.

The original input pi-network is long gone. Most of the articles on conversion say stuff like "remove N turns from the original 10 meter input coil". Can anyone tell me component values for the 2 capacitors and the inductor for a 6 meter input network ?

Thanks and 73,
Steve, N2IC
