I believe so Pete. Take a look at the picture in the write-up. Certainly at
least three are in series. It may be that it is three in series and those
three are in parallel with a second three in series.

No matter how it is built, we can see the performance result from the
curves.

filter scans

Hi Tod - I have read that the ICE filter is configured such that 6 sets of 
relay contacts are in series with the RF passing through the unit - that is 
bypass/bypass/bypass/thru filter/bypass/bypass.  Is this true from your 
observation of the innards of the 419B?
