Lost the shunt on my amp hv meter. Slapped 2700 volts across the meter. Needless to say, pretty much cooked. Great fireworks for a split second. I would like one that is square but doesn't have to be. 3, 4 or 5 kv will do the trick. I will make a shunt to match the meter so the movement voltage does not matter. Regards, Gary...WZ1M
