P**B
This protection circuit needs absolutely separate 30v ac PS.
Device is working alright but ac supply should be connected ground to ground to the one half of the transformer, but transformer should be 30-0-30v AC other wise separate 30v ac winding or small 15-0-15v ac transformer required.

Not as described
This product claims it protects loudspeaker, but this is restricted to 12V max 30V but Amplifier works on 50V 0 50 V (100V). If I give external supply 12 to 20V it doesn't work..
