Take a good look at that 2K resistor. I just did some fine tuning on an AK 559. On the AK the resistor appears to be a shunt - but the meter will not function with it open. My meter had become somewhat less sensitive, probably due to loss of polarization of the vein. I was able to increase the movement of the meter by LESTENING the value of the resistor (not intuitive considering the shunt function). Resistor value is now 1.5K and the meter moves through it's range.
