      Recently there was some concern about the power of the Blue lane. I measured the lanes this weekend and it seems they are ~mainly balanced.

      TEST CONDITIONS
      —  Power supply analog meter set to 11 volts, and the meter below the monitor showed 11.00 V.
      —  I plugged in the cleaner truck controller and the monitor meter then dropped to 10.92 at full Pot (hey it’s 420 some where :). The 0.08 ‘draw’ was probably just due to the resistance in the wire from the pot to the XLR plug (the microphone cable wire is only #20 guage; which works fine for the swifter Truck but is skinny for racing – WTH  – has no significant impact to the measurements :).
      — Residual voltage on the meter was +0.08  (you’d think this offsets the Truck pot loss but … no does not work exactly that way … coincidence I assume Watson).

      MEASUREMENTS  (each done x3 times)
      — BLUE measured 11.05 less .08 == 10.97
      — YELLOW measured 11.04 less .08 == 10.96
      — GREEN measured 11.08 less .08 == 11.00

      So Green is not only topographically the most challenging lane, but is slightly hotter (0.04 V) than the other lanes.  The voltage deltas (+/- 0.1 and +.04) are probably due to various factors including:
      —  slight length differences in the feed wires to the braid-drops (probably an Ohm or less difference.)
      —  Surface impediments (braid juice, dirt, general schmegma) not letting my probes get a 100% perfect contact with the braid;  (Altho my probes have pointed ends and were making good contact).

At 4-years old in Pensacola I repaired my steering linkage on my Ford Pedal-car. Dad later converted this car to a Blue Angel with ailerons and elevators with a working "stick/yoke"; the rudder was controlled by the steering wheel. I like all motorsports - I grew up going to a NASCAR Feeder track with Sportsman and Modified classes, and was lucky to attend drag races in 1970 at Orange County Raceway. My first solder-iron was a Christmas gift at 9yo; I modified T-Jets to be AFX spec before AFX Cars were in local stores. I rebuilt a few tractor & car (SIMCA) engines plus transmissions by 15yo (I still have my ring-compressor and valve spring tool) I am a former mountain and road bike geek & perennial sound engineer.
