As far as the correct voltages at points, there is a schematic with the voltages listed on his site.
As far as the wiring goes for the meter, if you believe there is a problem with the metering, you can post a decent rez pic of your wiring so we can see whats going on there (if anything).
The calibration videos are pretty accurate (although i've kinda shorcutted the third one as far as setting the drop up a bit easier).
For calibrating, you want the attack either fully CW (all the way up) or off (when he talks about shorting the pad to ground to bypass compression, that would be when you click the attack to the off position instead of jumping the pad to ground) anything short of fully up or off you're going to get a delayed reaction from any change you make internally. which is why at around 50 seconds or so he says that the position of the attack knob is irrelavent (because hes got it out of circuit with the short to ground) For those of us using the HAIRBALL kit with the switches and the "switched" knob for the attack, we turn it completely CCW (or off) for the first step in the calibration as stated in the video. Your release should also be ALL the way up (CW) to avoid delays in meter response (when in circuit). (notice the settings he has on his unit around 1:50 of the first video attack and release all the way up)
Try it again with these settings, see if that helps.
