Identification
- small green PCB with top side text label of "medialab/POT2a.pcb", "021705"
Assembly Variations
- 1 : Vref = 9.92V used stacked of resistors for RR2,RR3 : RR2/RR3= 2.9717
- 2-8 : Vref = 10.0V, used RR2=3.00k, RR3=1.00k
- value of RO1, RO3 may have been decreased from 20k to allow greater adjustment of Voffset
- values of bypass caps (CD1-4) may vary
- value of RR1,RR4 may have varied from 698 to 1k.
