    Serge I have the same setup. Just use the RCA for PT and ignore the ALC. The most I hit the  amp at is about 55 watts. VE3DZP

    Hi again Serge,
    The newer AMP's have +12V relays that are low enough current ratings that you don't really need the ARI-500, some would disagree but the current to key the ARI-500 is probely pretty close to what the ALS600 uses.
    The OLDER tube AMP's (Collins, Drake, Heathkit, (basically old TUBE Amps) have about -170DC on the keying relay and these old amps do have to have the ARI-500 to keep the Negitive, High voltages and  >15ma @ 12V coil current out of the radio.

    glad it is working for you
