Here is what the IC-746 FAQ has.  
I'd love to add to the list.

Q:3.5.5 Where can I get an external switching relay?

        Yes.  If you hook up an external power amplifier, then
        you will need an external amplifier switching relay or
        circuit (see above).  You have several to choose from:

                Ameritron ARS 702
                Ameritron ARB 704
                MFJ ARB-702-I
                MFJ ARB-704
                W2ENY Amplifier Interface
                Yaesu FRB-757
 
        Users of older amplifiers (like the Heathkit SB-200)
        will want to check out the "soft key" modules from:

        Heil Sound makes a foot switch that can control both
        PTT and amplifier switching, in the correct sequence.

        KD9SV has a "Front-End-Saver" switcher that handles   
        extra antennas along with the amplifier.
