    2929I suggest a DB-9 female connector mounted on the PCB edge with pinout
    3030as follows (so a twisted pair cable can be used):
    31 
     31{{{
    32321 - output+ (J4 center) (through 100 ohm resistor)
    33332 - output- (J3 center) (through 100 ohm resistor)
     
    35354 - P2 (pot wiper) (through 100 ohm resistor)
    36365-9 - GND
    37 
     37}}}
    3838* Choose a panel meter (2-1/2 or 3-1/2 digits is fine) and figure out
