I just purchased a used Video 14 mk II head and I think there may be a problem with the counterbalance because when I try to tilt up/down the spring fights very hard against the tilt and tries to return to center. I mean REALLY hard. And it doesn't exactly return to center, it rests tilted back about 5-10 degrees. The only adjustment for the counterbalance that I can see is the red knob on the side that only has two positions, and neither of them make much of a difference. There doesn't seem to be any way to disengage the spring either. I've used Sachter tripods many times before and they normally stay where you point them but I know this is an older model so I don't know if it's supposed to be this way or if it's broken.
