Hi, I have a bunch of NOS meters I've collected over time. I'd like to use them in a new 6m amp I'm putting together, so I need to make some shunts... Anyone know of a procedure where I can determine the internal resistance without damaging the meter movement? or, am i SOL? Some are uA meters, some volts and some watts -- so who knows what the intended range was. Thanks, Gerry, W1VE
