Somewhat, I have both here to reference. The stubby type power tube will not work without transplanting a compatible hammer and bolt over. However if you find a long type trracer power tube its the same diameter as the hammer one, I just checked the other day because I too am looking for a power tube for mine.
Another piece of info you may appreciate is that the threads for the valve screw on a hammer seem to be standard nelson ones. My bladerunners powertube/valve screw/cupseal combo screwed right in so look into used nelson parts and get the whole set. Thats probably what I'll end up doing with mine.
