It is automotive resistive and (I think) 400 ohm. I can check if you like but the value you get should tell you pretty quickly. My 3300A runs low - mid 30's psi when hot.

Thanks Gary, I see what you mean now. That means that you could only use this on smooth surfaces because any drag on the casters will load up the travel stops on the nose gear. The fact that I was ...

Only bit I would change is "hollow rods up into rockers to rocker shaft (nothing to valve guides apart from mist)."
