I've been considering adding a PF-50T and either a PF-115HE or PF-210HE to my arsenal. But I could have sworn I read in some thread that the PF-50T will not work as a flip-top with these cabinets without some modification to the cab, that only the solid state PF's work without modifications. I've searched every way I know but can't find those threads. Can an Ampeg user verify one way or the other, will the PF-50T work with these cabs as is? Also, anyone find a huge advantage of one of those cabs over the other, other than just the personal preference of 2x10's vs. a 15? I've been playing 4x10's for a few decades now, and was really wanting to go with the PF-115HE on this rig for the different flavor. Curious though that the PF-210HE has casters but the PF-115HE does not.
