[AMRadio] Simpson 260

[CL in NC]

Thanks for the input from several of you.  As I mentioned, it is not the electronics of the Simpson meter, the shunts, resistors, etc, this is a meter movement issue, and I'm just feeding 250MV directly to the removed meter and not getting the required full scale indication.  You can simulate this by putting 250MV into the common and 50ua/250MV jack and the range switch in any position except ohms, but that has the 200K shunt resistor and the 5K series resistor in the circuit and I wanted to eliminate those as an issue, so disconnected the whole meter movement.  I did email Simpson and they said they hadn't made this meter in 40 years, had no parts,  and no longer serviced it.  Got one interesting suggestion that the magnet might have weakened over the years, maybe by being near an AC field, but my Eico, Conar, Heathkit, Lafayette, and Triplett meters have all been right there with it and they still work fine.  Glad to see the 30 volt battery is still available for the Triplett, about $16 bucks, but beats 3 nine volters rattling around inside it.
