Many of the members on here are working outside of their comfort zone doing this modification and I can't see why we need to make it more confusing or more difficult to achieve what they want to achieve. The photos below are all from members here who added a power angle to their Cubs without a power beyond valve and I'm sure they all work just the way they intended them to. Simply adding a P and T line to their auxiliary valves is the simplest and easiest way to get the job done with the least amount of cost and effort.
