[Premium-Rx] Introduction, and a RF-590A question

I can go take photos of how mine is connected but first let me ask you why you 
want it?  The receiver is very selective without it, and it is designed to make 
the receiver functional in an installation where there are multiple high power 
transmitters running while it is receiving.  You lose a bunch of sensitivity by 
having it in line.  I have a mod which uses the NB button to bypass the 
preselector and I've found over the years that I have not found a situation 
where I needed the preselector.
