    Yeah, sounds like ALC. Mine would peak to 600 watts max but was a little overdriven - would run full out at 500 all day as I recall, no problems.

    22watts should give an output of 350 watts with the kpa500 if your modulation is correct so if you have poor modulation and increase your power you are creating instability and hurting the amp by surging due ti in sufficient drive. You wii most likely find with a rtty or fm modulation it will drive the amp normally. You dont need alc connected to the kpa500 at all.
