Hi Guys, I don't particularly care for MOVs because of their inherent wearout mechanism. When the voltage across a MOV reaches the breakover point, the MOV conducts and turns the excess energy into heat. Problem is, its breakover voltage then increases and it will allow more of the transient to pass next time. If a MOV sees enough action, the equipment protection is compromised and you won't know it. They are cheap, however, and better than no protection at all. 73, Bob, WA9FBO
