Picked these up locally last summer, all original mint drivers (no pushed in dust caps here), great cabs. I purchased a spare set of X-overs (kept the originals intact), stripped them down to the boards and completely rebuilt with Madisound L-pads, inductors, Solens fast caps & Dayton resistors, all new 16 AWG hook up wire & gold plated binding posts. Improved the internal damping with open cell 1/2" foam. Sonofagun's quadrex grills finally arrived this week for the finishing touch. Hope to hook them up tomorrow.
