After Don's comment, I did some googling and came up with the following info. There's so much to learn about this hobby!

Not sure what brought this on but the teaching point of my post for those who would otherwise make current, voltage, saturation calculations for Inductors in RF service and build from them is to prototype first. ?My recollection in relation to Hans Summers LPF kits (nothing to do with my tuner design) is that guys are using them in amplifiers up to 100 watts... and i wonder if they have had the parts on the bench to really see the limitations of the filters. ?More clear?

Bill, Before you get too invested in small toroids consider that the tuner must deal with higher currents than an LPF. Saturation results from current, not power. 100 watts and high impedance ratios requires larger cores. Best to do the math before ordering. 73, ND6T
