You may notice, particularly in dot mode, the bottom LED on each meter of your FET/500 remain dimly lit when they should be turned off. This is a known issue with the LM3916 meter driver chip and newer more efficient LEDs. If you'd like to fix the issue, you can simply solder a 2K(ish) resistor across the two leads of the bottom LEDs.
