[Boatanchors] SP600 Meter

[jeremy-ca]

If you have to use a 1ma that fits properly you can always either modify the 
circuit which may be a simple voltage divider ( I dont have a SP-600 
schematic) or install a SS meter amp. A 1ma movement wont have the same fast 
action as a 200ua but in a pinch........
